I made missing part for 10mm internal diameter bearing and 5mm D-shape motor shaft.

Part between motor shaft and bearing is missing.

Sorry for the confusion. One base has a grove that can receive the cover better. It's up to you to choose which one you want. The thin ecc gear use 8mm ID bearing, the other one takes 5mm ID bearing. 8mm ID can have more room for the offsetting. The shaft part is really hard to print, I am use metal parts.

How is the metal eccentric part connected to your steppers shaft?

I (mindlessly) printed all the parts. It's an incomplete set. Missing the eccentric drive than goes on the motor shaft. Also there's 2 variants of the internal gearing, one of which has a very thin wall & didn't print properly for me. Plus 2 housings, and 2 end caps.

An exploded view would help enormously.

Hey I was wondering how I'm suppose to put this together I have been struggling for the past hour and nothing has worked so far please help. thanks.

See attached video. It works, but don't put too much power. I eventually melted all gears into one piece.

ya, but i still dont know how to put it together what order do they go to gether.
