Parametric precision screwdriver hexbits box

Customizable version based on Stewbacca's design. The toolbox section isn't 100% parametric - screwdriver/extension holes are hardcoded.

I've got at least three sets of these 4mm hexbit screwdriver sets so wanted a model to hold a few more bits, drivers and extensions.

Haven't printed it yet though as the slicer says it'll take 5+ hours even at 5% infill @ 0.3mm layer height and I'm debating if its worth it!
