5.5" Lapidary Disc Holder for Flat Laps

I made this simplistic design to hold my 5.5" flat lap discs that screw onto the righthand side of my 6" cabbing machine. 

The front three spaces accommodate the thicker, foam padded full faced resin laps, and the last two slots are narrower to accommodate a diamond lap and canvas polishing lap. 

This design is meant to be printed upside down without supports. I added four bumpers to the feet to make them anti-skid.
