Moonlamp with 21700 battery and USB C charging

I wanted to print one of these lamps, but didn't like the need for a wall plug, so I designed the inerts to fit what I had on hand (which is quite a lot as it seems…) I changed the diameter of the tube so that the LEDs aren't directly above another but are rotating - probably completely uneccessary, but if I am designing already, I might make it perfect. The slit on the side of the tube is for the cable from the battery. In the center of the coin-groove there is a place for a 3mm LED - I have ordered some dual color LEDs with common anode so that I have the charging status visible outside USB C: https://www.aliexpress.com/item/1005004343322427.html Standard TP4056 charging circuit with protection Step-Up converter: https://www.aliexpress.com/item/1005003112775752.html The switch: https://www.aliexpress.com/item/4001165826718.html Print without supports: You have to clean out the two holes, there is a 0.2mm layer across - that makes it possible to print it without supports. I took the voltage up to 10V - more than bright enough. Edit: Took the voltage down to under 9V - now all the LEDs are just drawing 22mA all together, so in theory the 21700 I used, a 4Ah one, can light this thing up for close to 200 hours If you have a 5V LED-Strip you can maybe ditch the boost circuit - but since I had the boost circuits and just 12V LED strips, I made it fit. Edit: I noticed that my newer charging-boards don't have a 1.6mm PCB anymore, but a 0.8mm one - I added a model for those.
