This is a simple 3d printed base for a LED growth light. First stick the LED strip centrally on a 3mm flat bar. All flat bars with 3mm thickness will fit. Use a metal bar to keep the LEDs cool. I have used a 1000x50x3mm flat aluminum bar. The 3d printed base features two 3mm slots for vertical and horizontal installation. To secure the base, simply put weight (eg powerbank) on it.

• Flat aluminium bars can be found in DIY stores
