FYI, the SE1 (the wrist light) is available to buy now. A bit of a niche device, but there are only 1000, so... if you want one, get it now.
It's clearly indicated on https://www.sofirnlight.com.
Four no-longer-needed tubes from a grow box (moved the printer), a few minutes in FreeCAD, some leftover white PLA (PETG for the middle one - using up leftovers)… and my daughter gets the shoe rack she was going to spend $40 for at Target. I might print some end caps or just use white stickers.
I truly appreciate and admire the amazing work I see on here. I just wanted to show that, sometimes, even really simple things (a rectangle and some holes) can be made by anyone and turn leftovers into something useful.
