House of Doolittle Marker Holder

This is a holder for the marker included with House of Doolittle wet erase calendars.

The current design is for magnetic mounting with a 2x2 grid of 1/4" x 1/4" x 1/16" neodymium magnets. Secure magnet with CA glue.

EDIT: The v1.1 model shifts the hole slightly away from the magnet mount. Printing on its face caused a flat below the magnet indentation that changed the inner diameter to 0.45" in it's "y-axis". The "x-axis" was measured to be 0.5".
SCAD file now included.
