Magnetic Whiteboard Pen Holder - Parametric

Simple magnetic whiteboard pen holder. Magnets must be added before the cavities are covered over. I did this by pausing for 2 minutes before the 13th layer was printed. I added these lines to pause:

;Move print head away
G0 X0
;Pause for 2 minutes
G4 S120
;Move head back to where it started
G0 X84

I used a pair of 4mm diameter, 3.5mm height neodymium magnets in each cavity. The cavities must have supports blocked on them using cura as the rest of the pocket needs supports.
