I needed a simple mount to hold a generic dry erase board up on the wall, but wanted to be able to remove the board if necessary. Has a screw hole for secure mounting, but command strips or double-sided tape should also work.
Used ABS for my print, but PLA, PETG, or ABS should all work as long as your whiteboard isn't very heavy.
Printed with the magic 5 settings: 55% infill, 5 walls, 5 top and bottom layers and it came out very strong.
