Parametric desktop organizer. Using OpenSCAD you can change:

• row/column size and number
• floor thickness
• well depth
• border thickness
• extrusion/support size
• 1 or 2 supports
• optional 2'nd section with different sized openings

... and more!

If you don't want to use scrap aluminum extrusion for support, then you can print plastic pieces.l

One tiny thing you might find missing is screw holes. I find the parts fit tight enough that screws aren't needed. Easy to drill if you need, or edit the file to add them too.
