self-extendable gearbox upgrade version
myminifactory
I design this extendable gearbox for convenient daily use. It is easy to make and use using 3D printed parts and ball bearing. Since I use a self-extendable unit, it is very easy to expand to the gear ratio which you want. Hope you will like it. Detail information on Youtubehttps://youtu.be/GilkxIRx7hc
