I needed a durable way to hold all my 18 colors of whiteboard markers and eraser. I made this holder in TinkerCAD to practice working with the geometry.
V2 is a bit narrower and the internal ridges help keep your markers upright.
I added vertical ridges to strengthen the print. If you have the original file, please disregard and print this beefed up one. This holds 18 expo brand or similar markers.

I had fun putting hexagons through the box to save material. I printed this without supports, so you can use this as a torture / overhang test for your printer.
Make sure your printer is calibrated. You can print with supports if desired, but I found I could print in PLA without any supports.This may be a good torture / overhang printing test.
I recommend a brim to hold it down.
