LED Diffuser cup from Scoreboard Project

These are the two pieces I used for my Bluetooth controlled scoreboard project at http://www.iliketomakestuff.com/make-large-bluetooth-scoreboard/

These were a quick fix for a problem so it's a simple model. The walls of the cup could be thickened a little for durability.

The caps were printed in clear PLA, and the cups were printed in black PLA
