- It can be hard to visualize just how large a helmet or piece of armor will be once it's printed out but in this week's video I'll show you just how to figure out those pesky file measurements, as well as your own head's, with a few tools you probably already have on hand (or if you don't can easily be 3D printed)
This video is LONG overdue and I actually meant to get this out last year but ... Bo and Mando had other plans for me lol

Just stumbled on this and it is very helpful! One thing that may make things easier...
You can calculate the exact scaling factor you need fairly easily:
1. Measure inside of helmet: across the helmet (Helmet X value) and front to back (Helmet Y value). Optionally you can also measure bottom to top (Z).
2. In general, you want to concentrate on the smallest distance of these measurements. Let's call this SMALLEST Helmet Axis Value.
3. Take your measurements of your target head as you showed in the video. We'll call these Head axis X value , Head axis Y value , and optionally Head axis Z value.
4. Use the head axis measurement that matches the SMALLEST Helmet Axis. (So if smallest is X, use Head X value... if it is Y, use Head Y value... etc)
4. To calculate the scale factor, use this formula:
Scale Factor = (matching Head axis value) / (SMALLEST Helmet Axis value)
5. Use Meshmixer or whatever program you wish to do a unified scale (of the Scale Factor value) across all axis.
Slicing a test print is a fantastic idea. Going to try that tonight.
Man! Such a good idea with printing a slice to test fit! I can't believe I never thought of that.
Thank you for all the helpful tips and sharing all you have learned from failed attempts or as Edison said ways that won't work. I'll try and repeat the correct ways as I venture into building a full Iron Man suit. With my first helmet I didn't consider the size and assumed it would fit most people, it printed perfectly but I guess I'm not most people (too small). I just rebuilt parts of a CR-10s Pro v2 and will be firing it up this weekend along with another printer I had.
You're welcome! Good luck on the Iron Man helmet, that's a heck of a lot of upfront work in just getting that suit and helmet scaled correctly, I don't think I'd have the patience for it myself!
This video has helped me over n over again
Thanks for this vid! Haven’t used mesh mixer yet, just started trying out armorsmith so I’ll see how this works too!!
You're welcome! Meshmixer def takes a bit of time to get used to, but I use it the most for stuff like scaling my own stuff. Armorsmith is great too, but I use that more for commissions and haven't had too much time to play around and get it fully under my belt to do a tutorial on
@@vaultfox thanks for the heads up and looking forward to trying it out!! Question for you!! I know you said as a response that you got your hubby’s mando suit together, did it also come with the calf leather wrap and charge straps/holders too or did you make those parts?! Would love to get into leather work but want to get 3d printing and metal lathing down first as the 2 take up a lot of time researching and tests alone lol!
Top tier tips.
thank you!
All of this is useful, as I just got my daughter (who's 12) a printer this year. She is hyped to go to local events and halloween. I got so much more to learn learn learn. 😁
wow that is such a cool gift for her!! it can be overwhelming for sure, but hope some of my vids help at least :)
Interesting video, I never realised meshmixer had measurments. I really should dabble a bit more with these things haha. I actually just go straight in and do test slices but this would save the guesswork. Thanks for the info...and the link for the caliper file. ;)
if it makes you feel better, I did the same for a looooong time. as much as I love 3D printing I am extremely bad at visualizing how large things are and would usually just go to test slices myself while guesstimating the scale.
This is awesome. Do you have any videos for how the visors are made?
thanks , very helpful this will be my first helmet ,
you're welcome, good luck!
this popped up just at the right time last night i printed the chest piece for my mando and it was way too wide and i was just going to guess and take it down 10% and try again but this will be much faster and cheaper
hopefully it helps! and like I mentioned I've 100% been there printing stuff out at the wrong size
You are a lifesaver!!
You’re welcome!!
@@vaultfox I have a cr-10 also. What settings are you using in cura
I have an extremely tiny head and this will be so useful for scaling. Also, the new prusa 2.6 version has a similar measuring tool for anyone who uses that software. How much space would you recommend leaving for padding? So lets say 23cm fits from ear to ear, would you go like 2,3 cm extra or would u suggest more or less?
How do you move the red line when trying to measure? I tried and it just keeps giving me this tiny little red line in the middle or where ever i left click and then it moves if i try to go to the other side
Thanks V.F.
You're welcome!
and always remember to triple check if you saved the right file on the sd and don't be like me... i had all the file scaled right.... i had few problem with the printer so i had to change few settings in cura and..... i forgot to scale again my mando helmet Q_Q and i just noticed now after i printed 3 pieces and only miss the face part.... it should go in, slightly tight on the nose but it should go.... so tnx to you from now i will change the way i scale the 3d model, better scale it, split it and have all right saved from the beginning on meshmixer ready to go instead of do all on cura
oh maaaaaaaaan, I have done this in the past as well!! my older PC used to freeze up CONSTANTLY when I was configuring/scaling files and I would lose so much work when it would freeze and other times it would save halfway through on the SD card and would just STOP while printing. oof.
Lol same!!! I started renaming or add the % scale on the file name lol, I had 4 different sized files of the same print a few times for some friends I was also printing things for and that helped a ton as my printer won’t display more than 14 characters on its screen lol! Oh the learning curves of printing 🤦🏽♂️🤷🏽♂️😂
@@jedirogar instead i always added the time on the file name xD like Face 1D , Neck 6H and something like this because every time i forghet how much time i need for the print , in this way i can manage when to start the print, but yeah , better make folder/ files with the % scale as name . ( or better solution, buy a huge printer that can print in a single run instead of cut every time every files because they don't fit on the plate x'D )
@@like_a_pr3dat0r haha I like that!!
Yea I may bit the bullet and get the cr10s v2 for that very reason!! Took 19 parts for my Starkiller helmet so trust me I get it!!! Was looking into a large resin printer buuuuut that’ll have to be a bit later seeming for the size I’m after would still be around $4k, so larger fdm it is lol
This is the way.
Ty for tips
Going to be utilizing this video for my 5 year old daughters Bo Katan helmet and armor and my 1.5 year old sons Boba Fett helmet and armor in time for halloween and our disney trip in December!
oh my goodness that is so exciting!!! I have some Bo-Katan videos too if you need help with her helmet specifically. Are you guys doing the Starcruiser with the armor?
@@vaultfox Unfortunately I don’t have the CR-10, i have the E3 Pro so I’ll probably have to break up the files for the armor but i will definitely be looking at your bo katan videos for guidance from printing, painting and all the process in between! I wish we could do the starcruiser as it would be an amazing experience but probably going to wait till they are a little older.
I am in the middle of printing up a Sabine Wren build for my 4 year old. Her tiny little helmet is adorable. Obviously it's not going to apply to everybody, but I ended up taking in the X axis more to keep her from having a bobble head. Apparently she has a very long head. lol
Also, check out Armorsmith Designer. Helmeted a ton with getting scaling done for all of the other pieces.
Great information!! But as a fellow glasses wearer, the black series helmet I can barely fit my glasses in there. How do you compensate for that when scaling?
Hello there, when I go to measure in meshmixer, upon clicking done the line disappears and there is no red line across the inner helmet. I’ve got snap to vertices on
Good tips!
Another option for those who do a lot of printing is have a 3D scan of yourself done if the option is available at a convention or through other means
I had myself scanned when I was at a con. It was not too expensive and the file can be imported to mesh mixer
thanks! and I've seen those booths at conventions, didn't realize they actually give you the file as well! I'll have to try that out next time I see one
Very helpful video I'm going to print out the calipers todayto mail to a friend who wants me to do a Boba Fett helmet for his 5-year-old son.
Hi there! So when I tried to do the measurements in mesh mixer, the red line isn’t working as it should. It is very small and doesn’t stretch. Any clue why this could be? Thanks!
I've watched both of your videos and I have no idea how to do that slicing a portion in Cura, everything I'm seeing is you have to use another program, so I am trying Meshmaker. What you said makes perfect sense though, but what about helmets that are printed in parts?
Not exactly sure what you're asking ... are you talking about slicing helmets into multiple parts for printing? Cause you can do that in Meshmixer with the Plane Cut tool, you'll just have to slice it into smaller parts using that tool
@@vaultfox I mean like when you go on thingiverse and the helmet is already cut into pieces, can you measure it then or is it basically trial and error at that point?
I have a question. I am trying to edit in meshmixer, kenobi clone armor for my son. I am editing the right arm gauntlet. How to I resize just the openings of the gauntlet? Where the gauntlet ends at the elbow, is the proper size. But at the wrist it's too small. If I try to edit the wrist...it changes the elbow. Is there something I have to do or a video that shows how to do what I'm trying to do?
For anyone who isn't able to use Measure the way she is in the video, hit Units/Dimensions instead (don't need to change anything) and draw a red line. That seems to do the trick.
awww just found this video, after i printed a helmet way too small, and then resized it too big, and wasted 5 days of printing on both. now to take some measurements and do it right,
i've 10000000% been there, hope the next round goes better for you!
For some reason I cant even use meshmixer they way you are? It stays grey on the bottom but wont allow me to move my helmet
I have tried this and if I go by the width of my noggin it is too small for me
How long is this calipers? How much centimetres?
Armoursmith is your friend. You're welcome :)
ehh, I've tried and this is much easier for me
Dont forget that the cheeks go inwards a bit and if you scale according to the base, it wont fit. How do i know? Because i forgot.
skip the math, to make centimetres to millimetres just put a 0 on the end 25cm=250mm
or if you have say 10.5cm drop the decimal =105mm
I'll do anything to skip the math, thanks for the tip!
It's crazy how my stl questions are always being solved with meshmixer
good morning ... how do I scale a batman helmet?
Do you sell your pieces?? I need some Mandolorian armor and helmet
Coming to this a bit late but I had to grab mesh mixer from waybackmachine. I'm sure it's an Autodesk snafu but luckily WBM had a snapshot of the website.
you can also use your phone and a 3d scanning app like ScandyPro if you have like an iPhone X or newer. it uses the facial reconition camera to take a scan of your head that you can export as a stl file. used it for my helmet currently printing! great video
I've been meaning to check that kind of stuff out for future projects ... def writing that app down. thank you!
@@vaultfox it’s definitely useful to have an extra set of hands to help you scan yourself haha. Flashbacks to me struggling for a half hour before just asking my wife to help me 😂
Oh thanks man!! Couldn’t remember the app one name👍🏾👍🏾👌🏾
oh man I can imagine!
Honestly, I've always used armorsmith and I assumed everyone else did too
I've used armorsmith here and there (mostly for commissions). I'm not really as proficient in it as I'd like to make a tutorial though
Only recently found out about it the last 3 months or so when I was looking for the “most accurate” mando complete armor files lol
That buzz in the background drove me so batty I couldn't finish your video :( ozone and other ai stuff can remove that.
Does mesh-mixer only work with pc’s?
believe so, unfortunately.
@@vaultfox ok thank you
Hello, So I recently purchased my first 3D printer. Today I decided to print out Boba Fett's Jetpack as a first official print. The total time was around 29 hours at a layer height of 0.04. In Cura I made sure that the back measurement was 12 inches wide. Upon the prints completion, I was sad to see that my print was 12 inches across,yet the rest of the jetpack was sized for a youngster. Before I got the 3D printer, I made my jetpacks out of PVC pipe and styrene, and that was the bases of my measurements. Do you have any suggestions for making sure my future prints will be adult size and not toddler size? Thank you, Daren
if I'm thinking correctly, it sounds like when you adjusted the jetpack on that axis so it was 12 inches across, it also took the other two axis's with it. there should be a checkbox option under scaling called "uniform scaling" that you'll need to uncheck, and that will make it so you adjust each axis independantly
@@vaultfox Since submitting this post I have learned a little bit more about Cura. Like you said, I found the uniform scaling. In addition, I realized that I miss measured my jetpack. Not a total loss on the initial print. I am thinking about making a Mandalorion costume for my German shepherd.
