I needed a tray of compartments to put screws in when taking laptops apart and the like so I printed one. I designed it with a noddy little OpenSCAD script so I can make one with long and thin compartments for airbrush needles or whatever.

I'll probably update this at some point to allow different thickness walls between compartments and for the outer walls and maybe for rounded bottom compartments.

The variables in the .scad file should be fairly self explanatory, compx and compy are the size of each compartment in mm; wall is the wall thickness (again in mm); nox and noy are the number of compartments in x and y and deep is the depth of each compartment.
