I liked simon5432's screwdriver holder and printed one. Unfortunately, one of my screwdriver was too large to fit in the holes, and I was actually missing a few spots for all my tools.
I redesigned this one in Fusion360 very similar to Simon's.
There is room for four more screwdrivers (total 13) and one of the hole is larger than the others.
I printed this Thing diagonally on my Ender3.
Use four #8 wood screws.
Print upside down, with the piece oriented diagonally on your print bed.
Use two or four #8 wood screws to fix to the wall.
Designed in Fusion 360. I provided the original CAD file if you want to customize your's.
