Bevel Gears

thingiverse

I required some gears, https://youtu.be/Rld1ZAs6YxA demonstrates them operating efficiently. Appear to fit reasonably well when assembled. Included the OpenScad file with settings from GregFrost's design.\nPrinted at .2mm layer height, 15% infill (final one I'll do thicker). One axis is designed for a 30mm hex shaft. The other is a 6mm shaft from something like a 37D motor.\nThe motor gear has a 3mm set screw hole that would need tapped to use effectively.\nThere are two different sets: 13:43 and 15:37, I'm unsure what gear ratio I'll need for BB-8 :)\nThe shaft of the little gear printed slightly too small, but I expect users to adjust the fittings to fit their project.\nThese gears are intended for my Lego BB-8 flywheel drive, we'll see how that goes when assembled.\nPrint Settings\nPrinter: FlashForge Rafts: Yes Supports: Yes Resolution: 0.2mm Medium Infill: 15% Notes: I printed with rafts because I'm experiencing some trouble with warping. I used 4 shells to try to achieve strong teeth. Which makes infill pretty pointless, though the middle of the big gear has some, won't cost much more to have higher infill if you use 4 shells. 1st attempt used a more normal 2 shells, which seemed fine for my application.
