Bit collet screwdriver with storage

This screwdriver is designed for use in more demanding applications (but it's still plastic). 
The advantage of the collet is that it holds the bit firmly in place, does not pull out when screwing and does not wiggle. 
It should be able to handle over 10 Nm of torque when conditions are met. 

Printing conditions - min. PETG, 3 layers, 15% infill, max 60 mm/s, random seam 

After printing, the strings should be carefully removed from the inner hexagon. The first few tightenings and removal of the bit may be more difficult (use pliers). 
Screwdriver can be damaged if not tightened sufficiently.
