- This is a 3D printed helping hands magnetic holder I designed for attaching to a vice for holding things while working on them (e.g. soldering wires to something).

Finally somebody 3D printed something practical!
Super useful! Need to make this when I get my 3D printer out of storage.
Very elegant.
Pretty neat! The only soldering I do is occasionally re-attaching electrical leads for the heating grids on some windshields. I guess one could print a plastic clamp that would attach to the windshield edge...
Excellent! :)
Good to see u back bro
Thanks. But I never left. I appear to be able to do only monthly videos these days, so it only seems that way sometimes.
Great to see another one of your projects. I can see I will have to get a 3D printer but I have no idea where I can keep it, too much junk already. Maybe I will wait till they bottom out on price 😊
They kind of already have, I really don't see them getting a lot cheaper than the $200ish they're at now for a self assembled kit.
I'd like to see a 3D printer in your hands too! Sure, makers like you and me can make anything without one, but it sure makes some things easier and frees you up to do things you might be reluctant to because of the difficulty.
If you're looking for cheapest while still being able to make a fair size, look up Anet A6 and Anet A8. They require some work on them to make them really good (there are a huge number of mods out there provided by a huge community) but they're cheap. And that info's a few months out-of-date so there are probably newer ones. I went with the slightly more expensive CR-10 so that I could skip doing all the mods and get straight to making what I want.
Big like 👍 👍 👍
Not sure two magnet in that configuration gives more force than one (I think it rather gives a longer field, but at the same intensity). IMHO, putting them in "U" with some plate connecting the N&S on one side would make a stronger magnetic circuit.
Having two magnets definitely gives a stronger grip than one. In fact, my first version had only one on either side and I had to add the seconds ones for added holding power. However, I agree that having north on one side and south on the other would make a stronger magnetic circuit. Sadly, the way the indentations for the bolt heads are for these magnets didn't allow me to do that.
I had made the helping hand with Rounder during the beginning days
Pardon my ignorance but is Rounder a thingiverse user (a search turned up nothing)? Do you have a link?
RimstarOrg Sorry but i haven't made video it was for purpose.
The rounder was worked as arm & the clip in the end
Well i have photo to share
Hi. Just letting you know that the links for "My CR-10 3D Printer..." and "3D Printing a Bicycle Chain Sprocket" are reversed. Great video as always :)
Hi. Thanks, and thanks for letting me know! They're fixed now.
Why use nylon fasteners? They are weak. So what if the fasteners are magnetic?
Good point. The only hesitation I'd have with that though is that the holes are pretty big relative to the width of the magnets and I've cracked a few at that point, though from impact. I'd be afraid to tighten them too much with something very rigid.
You can use paper washers. I have many left over from upgrading my motherboards through the years.
Or a piece of electrical tape, then poke the screws through the tape after the tape is attached, or the best solution would be to attache the magnets using cheap 5-minute epoxy. Although epoxy doesn't stick well to plastic, you prints have very rough surfaces where it counts. That way, even if the magnets develop cracks, they'll stay put.
Just suggesting alternatives for viewers that don't have nylon hardware.
I especially like the electrical tape washer idea! I'll get some use out of that.
Thanks for the suggestions. Not only doesn't everyone have access to the nylon parts, they're also expensive.
👍
Wouldn't it be better if you use vacuum stickers? The vacuum stickers can stick on any surface while the magnets stickers can only stick on ferromagnetic surface.
Oh, neat idea. I've never used them though. Can they hold much weight? I can see a problem if the surface you're trying to attach to isn't even, but it should work for most cases.
They can support huge weight, so much infact it is impossible for me to pull them out of the wall, you can only get them out if you lift one side of the sticker and let some air in. Other wise you need to be very very strong to pull them out.
You know I wish I could find the vacuum cups that my vice uses where you flip a lever over that pulls the rubber away from a surface and doing that it creates a vacuum that is strong enough to life about 8 pounds per square inch (if not more) but it requires a smooth surface.
Can you put a video on programming
Like python or C++
Oh, that would be way off-topic for this channel. I've even been sitting on some neural network programming ideas because this channel's topics are already a little diverse.
What does everyone think about that? The channel trailer says what this channel's about... would straying from that matter to you?
PS. I'm a novice at python and know C, but not all the extra C++ stuff, so I couldn't do those anyway.
Tons of other videos on you tube about Phyton, C , even Cat and Dog programming!!
Seems a bit overkill for something you can make with wires insead
sound needs improvement
Yeah, I think I need a windscreen for putting in front of my microphone.
Actually i think you need to see how to level audio and all other kinds of settings, your voice sounds a bit more silent than video
I've done quite a bit of leveling to get the sound I have. Not sure what you mean by voice sounding a bit more silent than video. I do run my audio through Audacity to remove noise.
His hearing aid batteries are going out so not to worry.
