I use my printer in a different room from my computer. (OctoPi) So a desktop status indicator was in order. (So that my wife can make requests if the printer is free.)

Included are rails sized for M3 threaded inserts (marked TI) or undersized for an M3 screw directly into the print.

Print 2 endcaps, 3 rails (of your choice). You will need 6 - M3x14 for threaded inserts, Longer for screwing directly into the plastic. If the panels are printed at 0.2 mm layer height, the top 2 layers can have a color change for better legibility.

My print is in: 

• CC3D Silver PETG for the frame
• Jarees Black PETG For the lettering
• Ataraxia PETG for the panels.

A blank tile is supplied for you to customize. You can use it as a “busy” indicator for your desk as well.

At the request of a co-worker, I have added a NOPE tile.
