Lithophane Holder - Round

For the Lithophanes you need to use the site http://3dp.rocks/lithophane/. Chose the outer Curve and use the settings as seen in the thingiverse pictures. There is also a picture for the dimensions “Lithophane_dimensions.jpg”. It must be the same ratio as the picture (4096x2734 px).

For controlling the LEDs I used a WeMos D1 mini. The Arduino code is also in the thingiverse files. Edit the code to fit your WiFi settings (password and SSID). In the Blynk app add the zeRGB and edit the Pins. B D0, G D2, R D1. Also adjust the range from 0 to 1023.

For the electronics follow the wiring from the picture. The switch just gets wired between the +12V or GND and the other parts.
Support me by buying the parts with my affiliate links. I used almost 2 rolls of filament for the different variations.

Update:
V5 – lower Distance between both parts, so the gap between the upper and the lower parts is smaller. Also lowered some tolerances for the bearing
V6 – added a spiral cutout for
