This works well with all LED strip of 10mm in width.
The bar is 30 cm in length and is printed diagonally. The 30 cm in length matches the voltage "cut" lengths for far most LED strips.

The work is based on user “Gigante” on thingiverse, but was too narrow to fit most LED strips today - [https://www.thingiverse.com/thing:3316724](https://www.thingiverse.com/thing:3316724)

Prusa mounting instructions

You can mount it backwards and it wont hit sample spool holder provided by prusament:

(fits well and tight on the Prusa MK2/2.5/3 frame)

Electronics:
I've used a 24V to 12V converter mounted right above the PSU with double-side adhesive tape in a small case for the converter. 
A similar converter can be found on  for 24V to 5V LED strips.
Both can be found on AliExpress, eBay or Amazon.

NOTE: 
MK2/2.5 uses 12V PSU - so you can run the LED directly from the Einsy board.
MK3 uses a 24V PSU - here you need a converter or a 24V LED strip.

Print instructions

I have used PLA, but it is recommend to print the model with PETG or another high temperature resistant filament, due to the heat from the LEDs.

Nozzle size: 0.4 mm
Recommended layer height: 0.15 - 0.2 mm
Perimeter: 2
