I use a little stepdown-module (https://www.aliexpress.com/item/DC-DC-24V-18V-to-12V-3A-Step-Down-Module-MINI-Buck-Converter-Power-Supply-Circuit/32778770850.html) to reduce the voltage of my 24V-powersupply to provide 12V for the LED-stripes of my Hypercube Evolution.

Therefore I created a small case to mount it on the 3030-profiles. Just fix it with a M5x18 and a M5-hammer-nut.

Feel free to print it and have fun.
