I got some cool filaments from the Dutch company Colorfabb including copper, bronze, bamboo, and glow fill.

The copperfill is my favorite as it polishes to a golden shine.

I needed to organize all my rotary bits.

So I designed a custom bit holder. I think it looks like 2 gun cylinders.

Printed some big numbers with the bronzefill.

The bamboofill looks like wood. I used it for the plaque and the knob. I glued small copper numbers on the plaque.
