Starfleet Delta Insignia

I made this for my grandpa who is really into Star Trek. This is the delta insignia that is so famously known.

I modeled it to have a hole on the inside that you can put a 15mm x 3mm magnet into. 

The gcode that I provided already has the necessary color changes in it to stop the printer to put in the magnet and to have the black and gold colors of the insignia. It has a total of 3 stops in the print.

I've also provided an .stl, .f3d, and .step
