7 Segment Mechanical Counter, Version 3.0 HUMAN TOLLERANCE

I found it difficult to insert the various disks (cam parts) into the 2 respective pins (Cam_d1 and Cam_d2) so I redesigned the two pins increasing the tolerances by 3 tenths, so it should work for all printer

EDIT:  

 I found it impossible to assemble the various segments to the plate, I redesigned the plate and all the segments with decent tolerances. In any case I leave the solidworks and step files, so if someone wants to change the tolerances they won't have to redo everything from scratch as happened to me

increased tollerance
