t12 Gear for 8.5mm Drone Motors

thingiverse

I needed a new gear for one of my drones after it broke a tooth. Not finding an adequate model online, I opted to design my own. This is my first contribution to Thingiverse, and I am proud to be able to give makers a useful print. This gear fits 8mm drone motors. I used the addon for Autodesk Fusion 360 called GF Gear Generator with the following specifications: 4.2mm diameter 20 degree pressure angle 4mm height .8mm center shaft diameter (This must be manually modeled after generating the gear) I used PLA with an extrusion temperature of 208 C, 70 C bed temperature, and 15mm/s print speed. For bed adhesion I used brim support with a 3mm diameter. I'm new to 3d printing, so some of these settings may be further optimized with testing. I found these settings to be ideal after my 3rd iteration. I hope you makers and shakers find this print useful in your projects. Thanks for being awesome!
