Expo / Dry Erase Marker Holder

thingiverse

I was looking for an easy way to store my dry erase markers on my desk. The marker caps need to fit snugly so you can remove the marker with the cap staying put in the holder, assuming it's stuck down securely to the desk. Two sizes are available, one for three markers and the other for four. This part is meant to be glued or strongly bonded to a surface but it can also be placed on a desk without any issues. If you're using the three marker version and leaving it free standing, print the stand and glue it to the bottom as shown in the photos so it won't topple over. The four marker version doesn't require a stand even when not glued down. The expo_cap_test STL is a test print to figure out if you should scale up or down slightly to get the correct fit. I printed the models on a Monoprice Select Mini and Tronxy P802, and both were the right size, but it's still a good idea to start with the test print. Keep in mind that the tight fit means you can only insert and remove the marker cap a few times before the ridges on the cap will wear away and the fit will become too loose for the part to hold the cap in place.
