- fixed the short holder for a better print.
I wanted to create a light fixture that is functional and easy to install without screws.
I have an Ender 3 that uses 24v as a power supply instead of buying 12v LED's and using
some kind of power regulator or external DC adapter I used IKEA ledberg 903.026.87 that were on sale and work on 24v.
I cut the wires of the Ledberg and connected them to the free terminals on the printers PSU.
