While browsing printables I found a few neat designs for magnetic dry erase marker organizers, but none that fit my exact needs. I decided to try and put something together in Onshape that matched both my requirements and my available magnets. This was the result.
It's a simple design meant to hold 5 dry erase markers (the larger thick line versions).
