We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
This is a modified version of Wade's gear that has the advantage that you only need to file a small indentation on the motor shaft rather than two precision flats.
The hole is exactly 5mm so it will come out too small when printed. This is deliberate so that it can be reamed to exactly fit the shaft. If you haven\'t got a reamer you can use a drill.
Insert an M3 nut and a 6mm grub screw.

So what's this mean?
We're sure nophead would love to see what you've printed - take a photo and share it on Thingiverse as a Make.
To post a Make simply visit this Thing again and click I Made One to start uploading your photo. You can also download the Thingiverse Mobile app (available via Google Play and Apple App Store) to take a photo and upload your Make right from the app!
