Simple but compact wall-mountable caddy for white board tools with capacity for holding up to 3 markers horizontally (so they don't dry out), an eraser, and small accessories on top (e.g. small sticky note pad, paper clips, magnets, push-pins, etc).

There is a recess in the back designed to fit this 3D-printable wall anchor by @LoboCNC. The back is sufficiently large to fit a couple of command strips on, too, if preferred, and the flat bottom allows for it to sit on a table or desk as well.

This should be a pretty simple print with no supports required. 

The included photos show it printed in Voxelabs’ PETG ("burnt titanium" is the color) with the Prusaslicer profile for Generic PETG. There are some very minor sags near the openings with this, but even so, they're not problematic. If desired, you could place supports manually to support the tops near the end of the tube, but it's not necessary. 

Since this filament has a low coefficient of friction, especially against the smooth walls of the marker body, I also put down some Duck brand friction tape on these. A bit of paper would likely do the trick as well.
