Screen print frame

This is a magnetic screen print frame that is used for cookies and other baked goods.
There are two parts to the frame to accommodate two thicknesses of cookies (3/8" and 1/4"). The cavities in the corners fit harbor freight magnets.

Printing:

I printed in ABS with 25% infill. Printed with the cavities facing upward and no supports are required. Glued the magnets in with CA. Very simple and PLA would also be fine.
