A simple and easy-to-print LED light bar for the Prusa MK4. From the original design, the arm was adopted, and the holder was modified so that the beam can be easily inserted but still held securely.
The beam itself and the diffuser is a redesign. A 24v LED strip is used as  light source, connected directly to the power supply.
Printed with MK4 profile "0.20mm STRUCTURAL"  in PETG. Any other filament is also fine. Print the diffuser in transparent PETG, with a slow print speed of 20mm/s for better transparency.
