I needed something simple to organise my collection of hex keys that I use for my 3d printers. This has 15 slots of different sizes plus 2 screw holes for mounting. I printed mine of a Voxelab Aquila x3 using Elegoo PLA+. Its quick to print (~1hr) using a 20% infill (which is probably overkill!)

The original file was made in TinkerCad
