I created this very simple thing to use a cheap LED Strip wrapped around, inside the Moon Lamp (https://www.thingiverse.com/thing:3532973)
I used PETG, and even after 24h nothing was remotely warm enough to deform anything, PLA miiiiight be too weak, idk (for the Lamp as well in any case).
The Podest/Base can be out of PLA, of course.
Works pretty great, the Plug is screwed in and has a hole for power-in barrel connector, together with the Podest it's onto the Moon with a few screws.
