First off, thanks a lot to @moon and @solidgeek for the work they’ve done, I’m basically just rehashing a lot of what they’ve done, so there’s no innovation here.
I got tired of always having belts that are too long or too short, and motor mounts that are either bending or don’t fit well, so I figured it’s time to make my own parts!
The mount is basically the @solidgeek 3d printed mount with an extra hole. The gears are standard spur gears from McMaster.
It’s all printed in PLA for now. The gears and motor mount are actually very sturdy, if anything the motor mount is too stiff, and vibration might cause delamination. Final versions will be printed in PETG with 3mm steel rods. The wheel gear is weak and will need to be redesigned, probably with through-bolts.
I’ll add pictures of the printed parts once I have them assembled.
I have designed a 3D printed gear drive, and in my experience Taulman 910 nylon is the only filament i found strong enought. Tried both PLA and PETG, and these were far from strong enought…
Er… I am not sure. I am not comfortable with the fact that it is 3D printed. But I would trust heat treated steel. And the motor plate, one bad interaction with a rock or bump wouldnt be great imo
I saw a picture of your broken motor plate somewhere on this forum. Thats what I would be scared of too. You could reinforce the plate with steel rods like solidgeek did with his build but even then…
I am planning to use aluminium for my gear drive and carbon fiber for quick testing.
I would use carbon fibre if I could but my design might not allow it. And it also makes sense to use aluminium since it reduces the amount of parts I need by 1.
I have a contact in China. I helped @FredrikHems with his stuff too. I have made several stuff with this company and my experience has been pretty good so far. If you need help lmk
The teeth might be fine. @MoeStooge is a crackhead and has used 0.8Module gears so if its good for him then it should be good for anyone. Its the 3D printed part thats no good
