Print-In-Place ratcheting screwdriver

So after I took on Martin Rigatoni's challenge with this screwdriver and LoboCNC promptly took me up on my unintended challenge with a much improved design and we saw many more _ designs by members of the screwdriver gang I wanted to return back to the basics and:

Keep it simple stupid

another one, a literal last minute entry.
It's still under 1h printtime, better ratchet, still not reversible, keychain sized and now PRINT IN PLACE. Designed for 0.3mm layerheights and 0.5mm extrusion width (Prusa .3 DRAFT profile with .4 nozzle).

It's still got that rear socket for screwing things the other way ;>
Also featuring 12 compliant springs to keep all your 4mm bits in place.
Tolerances are 0.15mm radial and 0.2mm vertical. Best results with my attached Prusaslicer .3mf file with seams painted as not to interfere with the mechanism.

AFTER PRINTING GIVE THE SHAFT A GOOD TWIST, OK. 

thanks to LoboCNC's genius ratchet design it's basically indestructible so just go at it! You'll need another screwdriver with a 4mm hex bit though to excert enough torque to break it free. Sadly that means that this is not a bootstraps screwdriver; you gotta already have one… unless you were to print a 4mm hex key with leverage….
