Expo Marker Case

Erasable Marker Holder. I use this case to carry erasable markers for my consulting sessions. The lid combined with the O-ring retainers makes a great stand to hold the markers in place and organized. I've modified mine to include a cut-out for a company logo on the back of the case with a printed insert of another color. The case pins are glued in on the lid and case with cyanoacrylate. I'm using base PLA. I like Micro Center Inland PLA for this print. PETG or PLA+ would be less brittle, but may shrink more. I use a -.7mm offset on the logo insert with a .4mm back to glue the logo in from the inside of the case.

I print with tree supports to keep the holes round. You may not need to do that.

Also, I'm printing in an Aquila C2 but that option was not available on the Thingiverse drop-down.

I use a brim, not a raft.


Use a 1-1/4" OD, 1/16" thick O-ring for the retainer with heat shrink tubing for a sleave.
