After getting my new heat set insert tool, I needed a way to organize the tips which come as loose parts. So I made this to go in place of the original cap. Picked this one because it is made from 20x20 parts so it would be easy to modify if needed.

Use 4mm brass inserts and 4x12mm screws that go in from the bottom.
You can make this as a simple two color print.
