Holder for 4mm hex bits

// EN:
This is holder for small 4mm bits. With it you can use your small bits in your favorite battery screwdriver.
I was unable to broke it in 3 months of use. :)
Made from ABS, and give it cold "acetone bath" (this is important for strength!) for 2 hours at 25 deg. C.
Depends on your printer's calibration you may have to enlarge nut part by X and Y axis (and not Z!) by couple percent.

PS. Please post your photos "I made one". :)
