Simple case for the Arietta G25 made by Acme Systems (http://www.acmesystems.it/arietta).
The holes are set for a standard M3.
Exposed hole for reset and one for the LED.
I use a short piece of clear filament to act as a light pipe, which works remarkably well. I also used a color changing filament for the inlay graphic, which is awesome!
Should print just fine as is. You may need to add helper discs if you have curling problems.
