REVISION 3 (6/7/2023):

Added a low profile frame designed to fit 100x150mm lithophanes. Should be able to print without supports, but if anyone has issues let me know.

REVISION 2 (5/26/2023):

Rev. 2 uses the same tea light, but with the candle part removed. You'll see in the images that the inside is just the LED now. I designed the cutout so the base of the tea light pops in without glue. You'll need a small Flathead or something similar to pry the top of the tea light off, then just press it into the slots for a seamless look. Planning to build on this with shallow boxes and scalable frames in the near future.

INITIAL RELEASE (5/24/2023):

This is a pretty simple way to backlight your lithophanes, and all you need is your printer and some LED tea lights. I plan to create multiple types, and this one is likely to see some improvements, but I hope you all enjoy this first one!

The slot was designed to be compatible with a few different sizes of tea lights, but I purchased non-flickering bright white LED tea lights for mine from Amazon. https://www.amazon.com/flicker-Flameless-Tealights-Battery-Operated-Decoration/dp/B009E1UPCE/ref=sr_1_6?crid=3NBWJFV510QSW&keywords=flickerless+led+tea+lights+bright+white+agptek&qid=1684938045&sprefix=flickerless+led+tea+lights+bright+white+agpet%2Caps%2C153&sr=8-6

These were designed to fit lithophanes of a particular size. When generating your lithophane, ensure the dimensions are 100mm x 71.45mm. The maximum thickness should be around 3mm to fit into the grooves properly.

Simply go to the lithophane generator and upload your image. I used the color lithophane generator, but you can do this with the basic flat lithophanes as well. Crop, adjust or edit your litho as desired and print. Once you have the lithophane and you've printed the housing, drop in two LED tealights and voila!

Print Settings:

• 0.2mm layer height
• 6 Walls
• Default profile
• Support on build plate only (For the tea light slots)

Instructions:

• Remove the outer cover of the LED tealight and place the lights into the slots using the pegs that hold the electronics to the plastic housing of the tealight.
• Slide in your lithophane of choice.
