This is a desktop organizer for my wife’s clay tools. Of course, it holds pens, pencils, markers whatever else fits.
I designed it asymmetric and so the holder can be rotated for some added ergonomics because I thought it would be cooler this way.
You can use the pin to lock the rotation you want. The holder can also be removed from the base if desired.
Has 20 Slots, each slot is 10mm wide, 80mm deep.
