Summary

I wanted an expo marker holder for my new white board. When I export stl files it often messes up the scale. I just scale it up by 25.4. I designed this model with a dovetail and its calibrated for my printer. I think if you had a better printer you might have a bit of slop in the dove tail. Also the holes for the markers are a bit lose mostly due to the conical shape of the marker.

I include the Inventor files. All of the dimensions are on the original sketch so it should be easy to edit.
