This Print houses an Node32s Microcontroller, USB-C Breakout Board, 8 Pixel Neopixel (WS2812B) Ring and holds an Lithophane. You can programm the Node32s to light up the Neopixel Ring in any color and do animations. If you have a home assistant install at home, you can integrate it with esphome to act as a smart lamp.
The USB-C Breakout board is a random one i had lying around. In the case there is not a lot of room so if you want to print this, i reccomend to size the compartment for the microcontroller up a bit to fit all the cables!
The USB-C Breakout board needs two 5,1K Resistors from A5 and B5 to Ground to indicate it needs 5V.
To generate the Lithophane i used this website: https://3dp.rocks/lithophane/
I uploaded the picture i wanted to use (1280x1280px) and selected the “Outer Curve” Preset. I Changed the “Maximum Size” to 80mm and selected “Positive Image” rather than “Negative Image”.
The holes are for M2 Inserts from ruthex: https://www.ruthex.de/collections/gewindeeinsatze/products/ruthex-gewindeeinsatz-m2-m3-m4-m5-sortimentskasten-70-100-50-50-stuck
The Lithophane sits slightly tiled so it can be nicely viewed from the desk.
