This is a little model that i made to attach a light to my Ender 3 V2 so i could have adequate lighting for time lapses and viewing using octopi, without needed to leave the room's light on. Made in Fusion 360. 

Works Universally across many different printers, and uses the standard camera threads.

The threads tend to snap if you tighten too much, so be careful with that. Printed using PLA at 205 degrees, 60 degrees bed temp, and 0.2 layer height.
