This is a tool organizer almost entirely tailored for my own tools sitting on the desktop, however, I'd still like to share it in case any of you find it useful.

It has:

• 10x 11mm holes for pen and slim tools
• 5x 16mm holes for chubbier tools
• 2x wedges for small pliers or side cutters
• 1x open platform for small stuff such as screws
• 1x side pocket, you can use with small things or put a small drawer there

Print as it, 20% infill, no support needed. Pry away the supporting pylons inside the pocket after print.
