This is my first try to build a printable robot arm.
I was inspired by the demo of zortrax, but it’s my own design.

It is not tested yet, I’m still printing.
It should fit together but.
There are 8 608zz ball bearing required to mount the arms.
2x M8x60mm and 2x M8x65mm screws and 4 Nuts (best case self locking)

The main motors are Nema17, for the forearm I plan to use a Nema11 with a planetary gear.

The screws to mout the parts together are M4

first test of the basis with the first joint:

I updated some files… most should fit now, but still a work in progress.

all parts are printed:

The second part:

I started a hackaday project:
