Simple LED light mounts

I needed a way to suspend some LEDs (Ws2812b's) on my printer, but most available designs didn't fit what I wanted, so I made a very simple straight bar with a profile on one end to fit the Ender 3's 20mm aluminium profiles. I simply printed 4 copies, stuck one strip of 4 LEDs onto each, wired up some connectors and powered it all via an Arduino Nano.

(I might make some quick cable holders and/or Arduino housing to go with this in the future)
