iFixit tool holder with skadis mounting. It has several square and rectangular receptacles for small tools, hexgonal slots for bits and two orifices for ifixit screwdrivers. I printed it using PLA+, 15% infill and works just fine. MODEL REQUIRES SUPPORTS TO BE GENERATED. The small dent you see at the bottom left of the front face in the picture is an experiment where I tried to embed a drawing. The uploaded STL model doesn't have this, it's plain.
The author remixed this model.

plomdawg iFixit toolkit holder edited to modify the number of tool receptacles, add 2 screwdrivers, bits and some other stuff. Added hooks for skadis mount.
