My first practical design I've printed, needed a place to put my whiteboard markers and this was a crazy simple solution. Works just as intended with a nice level of grip that is quick and easy to snap the markers in and out of. Mounted with 3M "Command Brand" double side adhesive strips, so that it can be removed cleanly if need be.Printed in white PLA as orientated in the STL with following settings: Layer Height: 0.2 Shell Thickness: 0.8 Infill: 10% Print Speed: 60mm/s Support: Brim Note: The one in the photo actually printed with minor curling defects so I'd recommend printing it on it's back with a raft if you have adhesion issues like I did (even with painters tape), this gave me a pristine result.
