Pen Screwdriver T3

1/4" hex bit precision lock
Cap precision lock
Cap grip
2X 1/4" hex bit (25mm) housing

NOTE :
May be that is a little difficult to insert P2 through P3, clean the parts with a small cutter and retry.
I used PLA flex for P4, is better but is ok also with same material of the others parts. I tried to print with pla, pla+, petg. I printed all the models at low-speed and for pla with max cooling. Cura engine, Nozzle 0,5mm, Layer 0,25mm for P1, layer 0,2mm for P2 and P3. For P2 and P3 i used fill 0% (avoid zig-zag movements) and for P1 fill 25%.
