Magnetic Marker Holder
by buckyball, published
A small piece which holds a cube magnet and a whiteboard marker together. No glue is necessary.
1) Measure the diameter of your marker and the side length of your cube magnet. You'll want a tight fit.
2) Update the values in Customizer.
3) Print the piece.
4) Slip the marker and magnet into their respective holes. The poles of the magnet should be tangential to the marker.
