A fully parametric lithopane frame that includes a puck light for back lighting. It's a simple 3 piece design (with lithopane) that snap fits together.
To start, head to https://3dp.rocks/lithophane/ and upload a photo to convert to a lithopane stl. be sure to have you Image setting to 'Negative' and add a border to snap into the frame.
The frame and back can be customized to the size you need in Fusion360 and will update both automatically.
For the puck light, I used this one: https://www.menards.com/main/lighting-ceiling-fans/indoor-lighting/under-cabinet-lighting/patriot-lighting-reg-led-plug-in-under-cabinet-puck-light/0005-0234/p-11060051207651480-c-7490.htm?tid=-4317509416761007608&ipos=3
