I designed this for a You3Dit.com request. I referenced the cap design/dimensions from kielerrr’s Fast-Draw Cap Marker Holder on Thingiverse, bought an EXPO dry erase maker to measure and test with, and created this cap that can be pinned to the wall, bulletin boards, pin boards, etc.
NOTE: As @kielerrr mentioned in the comments section on Thingiverse, these caps may not be tight enough to keep the markers from drying out. I’ll try to make some adjustments in the future to see if this issue can be resolved or not.
