Print:

• 1x main-hull (with SUPPORT material! - look at photo. In this part you'll put in LED strip) - with support
• 2x holder-left (or you can print one left and one flipped) - no support
• 2x connector (if you want to have longer holder for lamp you can print more of them) - no support
• 1x hull side left (side cable cover) - no support
• 1x hull side right (side cable cover - has opening for cable) - no support
• 1x glass.stl (WITH TRANSPARENT FILAMENT! - if you dont have it, dont print it - it covers the lights) - no support
• Print at least 4x screws with nuts or buy / use any other with specs:
  • 9mm diameter
  • 20mm length (15mm thread and 5mm nut)  
  • ( I used: https://www.thingiverse.com/thing:193647 )

Assembling:

• cut LED strip on 3x 30 cm strips
• glue them to the main-hull one below the other
• use short connection cables or solder it (like me)
• cover it on the left and right with hull-side-left and hull-side-right
• attach transparent layer in the middle
• attach connectors and holders with screws
• attach all on prusa frame

Wiring

• I had connect it to my 12V power supply, so it goes on when I turn on my printer.

For frame I used Filamentum Vertigo Grey filament and it goes great with original Prusa frame color.
