StarTrek Shirt Pins

Pretty simple pins, the small cylinder with the cut slot is for the safety pin. The safety  pin goes into the slot and the Cylinder is then pushed into the pack of the pin. It prints for me as a pretty tight tolerance. you very likely will need to adjust in your slicer or use some sandpaper, knife, and glue. (i had to use a pair of pliers to squeeze it into place.

I achieved two color effect pausing the print at the last few layers, then printing in gold (also a gold sharpy works too

I have also found success having the pin run vertical instead of horizontal. That is more of a a personal preference

Also this idea isnt original, I got this idea from a different modeler. If I can find there model again ill attribute them here
