CNC

this project need a lot of screws washers and bolts from M8 to M3 the main guide lines are 2020 aluminum square pipes and 608z bearings, I have done mine in PLA and is working great (only as a plotter so far).

screws:

M8x16

M5x12

M4X12

M3X8

threaded rod M6 

M8 for the Z lead screw   

the motion system is 6mm belts for x and y with nema 17 motors.

i put the STEP file because the CNC can be improved.
