This is a hanging light that looks like a spool of thread. The fabric cord for the light doubles as the way to hang it as well as the “thread” that wraps around it. Depending on how full you want the wrap around the spool and how much needed for hanging/rigging, I would suggest at least 15' pendant light cord. 15' is what is shown (https://a.co/d/gXJfJyU), but recommend at least 30' - 50' if you want a more full looking spool and have enough to hang and plug into the wall.
The cap needs to be printed twice (one for the top and bottom).
Print in 0.2mm layer height. Enable supports for the “hole” on the bottom of the middle cylinder. Supports also for the cap's center hole.
