Motor Pinion M1 (Modulus 1) T14 with M3x5 Screw Grub

thingiverse

Hi There! I own a OpenRC Truggy and modifyed it to use a Mod1 Central Differential. I had troubble to find out a Mod1 pinion with 3.17mm bore and i had to search for an adaptor. I'm planning to build my second printed RC car and now cant find the adapter to use 5mm bore metal pinions in 3.17 motor shafts. So i gave a try to this [Modulus Gear Customizer](https://www.thingiverse.com/thing:2572111) and the result i think is very good! I substracted a cylinder from the exported customizer stl to be able to use a screw grub to lock the pinion in its position. The substracted cylinder was 2.8mm diameter and was good for me to strongly fit the screw grub. I have given full throttle from 0 and full brake from "top speed" to see if the pinion can do it's work without easyly breaking and there it is :) Also with the 1.1 KG extra weight of my FJ Cruiser Body!!! The creator of the modulus Customizer included 2 params to create a keyhole, but not a screw grub hole. It would be nice if he does, so we could directly create the final stl file for printing just in the customizer! Anyway if you need some help to get a pinion similar to mine but with a different number of teeth just say something! :)
