Arrma Granite Voltage Spur Gear

thingiverse

Arrma Granite Voltage spur gear. Mine stripped easily and so I designed this in Fusion 360. It seems to fit, but PLA didn't hold up very well. I think that is because of infill settings. I know a ton of people bought these for the $60 Black Friday special, so hopefully this will be useful to people. If you make it and try it out, leave feedback so I can adjust accordingly. I am putting it up here as a work in progress. I used tree supports. Update: PLA and ABS aren't holding up for the input gear part of this piece. I would like to try Nylon, but will need to do some upgrades to my Ender 3. Update: I added a v2 which has a slightly larger opening. I have not printed this one yet so I will keep v1 around since I know it works with some sanding. Update: Printed in ABS @ 50% infill and seems to be working well. The gear hole that the bearing from the closing case fits into is a really tight fit. You might have to sand it a tad. I will try to update the STL with the adjusted opening size.
