This is a holder for Sharpies to clip them onto a Skadis pegboard. You can alter the .scad file for number of sharpies and height.

The 45 degree cut in the print allows you to print it without support, and include the top and bottom supports

Thanks to t0b1 for the hook profile!

The code is kind of a mess because I added fillets with a minkowski, but you shouldn't need to change anything except the number of sharpies, and their size to fit different markers.
