This is a simple lantern I designed to work with WS2812B LED strips (or anything similar). I wanted something that looks great when lit up, is easy to print, and doesn’t need any support.
I printed all the parts using a 0.6 mm nozzle and PLA+ filament. You might need to play with the tolerances, or use some CA glue for assembly. For the cable anchor you will need some 10 mm magnets and some M4 worm screws.
