I used M4x12 screws to screw all the parts together.
Printed with 15% infill PLA+
Added the .f3d files for everybody too
Thanks for the model @David Herejt
The author remixed this model.
I just remixed the model a little to fix my needs more. Made the top a litte bit wider and deeper and added some more holders to fit my tools more effective. Lik the holder for my calipers with leather case, screwdriver, Bits, deburring tool from Meistergriff.
Also gave it a little bit more depth to fiy my M4x12 screws. The bottom also received some holes for hex socket head cap screws.
