Ring-gear & pinion for 450mm lazy-susan bearing
thingiverse
I made this for my robot project and it may be useful for others. It's sized for a 450mm/18" lazy-susan bearing that's often used on R2-D2 builds, though it will require custom holes to be drilled. Obviously print 8 for the whole ring. Solvent-weld or glue together. Ring-gear: 64T Pinion: 8T Pinion hole: 5mm with hole for M4 nut and bolt to secure to shaft. Video of it, and more info on my DroidBot project can be found here: https://droidbot07.blogspot.com/ https://hackaday.io/project/20153-droidbot-07-wheeled-quadruped
