Expo Marker Storage Rack

Just searching for a marker rack, didn't find one to suit my needs.

Composed in Fusion 360.

Marker board is non-magnetic, and screw holes were a no go, so sliding over the existing tray was my solution to some dried up markers.

The tray gap is a little loose, i am considering adding a bit of felt to the top and bottom of the slot to fix the OG, perhaps a nubbin in the middle for leverage..... oh well, REV 2 someday!
