This is the first entirely 3D printed Mini Milling machine ever, it's suitable for Dremel 3000, you have just to print the pieces, turn 3 handles ( one for each axis ) and you will have your personal functional manual milling machine.
This machine is very precise even if it's made in plastic, you have to put grease between the sliding parts to lubricate the machine and eliminate the friction.
You can see how this machine works through this link:
