3D Printed Cupboard Organizer
I designed and printed this kitchen cupboard organizer to hold Tupperware lids, silicone covers and pouches. It took 2 hours with Anycubic high speed resin, on the Anycubic Photon Mono M5s Pro. I'll put the file online at Cults3D and Printables.

DJI Toroidal Prop Test 37.40
zhlédnutí 9KPřed 2 měsíci
DJI Mini 3 PRO Toroidal prop 37.40 after some flow simulation optimization. These produce the same lift at the same RPM. Noise profile is looks similar with about the same primary amplitude, but with slightly lower harmonics. I wouldn't say they sound better, but slightly different. I will post a comparison video of the standard prop so you can hear it in the same environment, although keep in ...
Toroidal Propellers V4, DJI Mini 3 Pro
zhlédnutí 10KPřed 4 měsíci
Toroidal propeller test, version 4, Feb 2023 These were printed on a Form 3 SLA printer with Tough resin. They flew and had lower pitch noise than standard propellers, but they overheated the motors quite quickly. www.digitalproto.com

Solidworks motion analysis of an RC truck driving down a track fast enough to jump and drive around a 360 degree loop. This simulation includes springs with dampening, and a motor that ramps up linearly to 20mph.

Bonsoir vé faire commande DJI AIR 3 PRO
I've heard about these, they look weird but seem to work well. Thanks for the video. Are these going into production at some point in the future, or are they designed for a specific type of drone?
Any chance I could get your .stl or .stp file(s) for these? I would like to try printing some on my Bambu X1C with various materials. -TBoone at 0TX1
Hi. I'm still working to improve them with flow simulation. However, if it get them working well enough to be better than the standard prop, I already have some other parties interested in licensing the design. However, if everyone passes on buying them because they aren't that much better, then I'll certainly make them available for everyone to print. I would recommend using resin though. FDM will make a very rough surface with less strength in certain directions. You'll have to do a lot of sanding and finishing to make it smooth enough be of any value, and at that point the shape may have changed. It can be done, but it's best if you have sand blasting and painting equipment to get a good uniform finish. It's hard to find a material that holds its shape and then isn't so ridged it shatters at maximum RPM. But if I find a good resin to use and no one else is going to license and sell a molded/carbon fiber version of it, maybe I'll also consider selling them for people who don't have what's needed to print their own. Stay tuned and we'll see how it goes.

How much this drone???
About 1000
soon as I saw the word “Toroidal” I knew 100% it was going to revolutionary sound wise! amazing job, do you mind if I post this video in the DJI SkyPixel group?
You're welcome to post it. I have multiple videos with the progress over the last year. But the most recent comparison videos are where the design is currently at. Noise it's drastically different, and while they no longer cause overheating issues, they still aren't as efficient. I have flow simulations running in CAD right now and continue to refine the design, but I'm not sure if they will ever be better than standard props across all characteristics.
Very cool work, thank you.
Can I just buy toroidal props online and do the same? What do you mean you tested this for a year? Did it not “just work”?
I haven't seen any good ones for sale. The first versions just overheated the motors and had to land immediately. I made a new set every week for the last year to get them better and better. But they still aren't better than standard props.
wow that is soo much quieter than usual
definitely sounds quieter than my m3pro.
I posted a short of the latest version as well, after a year of modifying and testing. No more overheating, which is nice, but still not as battery efficient is the factory props.
@@digitalproto good to know I wish I could 3d print it but my normal 3d printer probably wouldn’t print it clean enough
@captainmichael787 True, FDM is pretty rough for propellers. You'd need to sand them a lot. My Anycubic was only $230 and has done an almost flawless job.
And the advantage, is what?
Last year MIT did a study on toroidal props that said they made less noise. So since then many people have been testing that theory to see if it's true or not.
Seems like broader spectrum prop noise but less efficient
Yeah, the sound tends to be a little lower pitch and slightly more quiet in general. But I have yet to get better efficiency. Trying to retrofit to an existing motor probably isn't the optimal way to design and pair the motor and prop.
Cant put into bag with these propellers
On the Mavic you always remove the propellers anyways because they have quick release props. But on the Mini 3, it isn't convenient to fit it into the standard bag.
@@digitalproto thanks for the info

it really does sound better then normal props
Brilliant. Thank you so much I was going crazier trying to sort this. So clear even I understood. Instant subscribe.
can you upload a tutorial video that shows how to move a klann assembly in the ground ?
có thể quay lại quy trình lắp ghép cũng như mô phỏng cho mình tham khảo được không vậy?
I see you did click origin, ah learning haha
Wow, really appreciate the offer of help, I may take it up some time ;) I have found my issue, when placing the post in the assembly its origin was not on the assembly origin. When creating the feature driven pattern, the assembly origin was used for the centre point, match the post and assembly origin and all done :-) now for floxpress :(
If you are stuck you could pack and go the 2 files and email them and I could take a quick look tonight or tomorrow morning.
I suppose there's the chance that they broke something since I did this video in version 2010. Is your cylinder fully constrained or just concentric? If it has the - in front of the part name then it's free to spin and maybe that is causing a problem of some sort. You could add a straight feature in the sketch so that you can mate one of the cylinder planes to it so that they can't rotate and hope that does it. I don't know what it would be other than that.
Thanks for the great video. I have followed your steps but with cylinders following the feature driven pattern. My cylinders don't stay mated to the surface feature. They start mated and finished mated but move away from the central post using a circle offset from the post. Any ideas? Thanks again
superb :) I couldn't find anything anywhere before now!
There was some trial and error to get it right and dropping it at the start of my simulation allowed me to judge if the reactions were similar to my actual RC truck. Does that help? You can also just use a damper separate from a spring and both of mine are linear, however you can choose other orders as well.
I made the shocks without a spring and then just selected the top and bottom surfaces of the shock to attach the spring in the motion analysis. If you know the K spring value and C damper value from your shock just enter them. I had to guess and knowing the weight of the vehicle helps narrow it down faster to a good number. I used K=6lb/in on the rear C=0.2 and K=2.5 C=0.1 on the front.
That is pretty cool! Thanks for sharing. I'd like to learn how you created the spring/damper constraints and the how you achieved their values
