A long time ago I printed a round lithophane and I didn't like the fact that I couldn't see the entire lithophane, so I decided to make a rotating lithophane lamp so that you could see all of your pictures on your lithophane.
BOM and code/schematics
- bottom bearing 1x ABEC 1
- stepper motor 1x
- tmc2208 1x
- arduino pro mini 1x 5v/16mhz
- brass inserts m3 - 3mm and 5mm length
-12v power supply 1x
-12v female plug 1x
- white led strip I used regular white
- 8x m3x16 screw - upper to upper lithophane holder and led holder to bottom
- 4x m3x10 screw motor mount to led holder
- 4x m3x8 screw - motor to motor mount
- a few passive components, look in the schematic for them.
Because the leds where getting to hot, I added an resistor between 12v and the leds. In the foto I used 4 100 ohm resistors in parrelel to form an 1W 25ohm resistor. I updated the pcb with an 1W resistor, the 1/4W resistor was getting to hot. You could use a lower resistor value, but please check that the led holder doesn't melt with the leds getting to hot.

Lithophane info
I created the lithophane with lithophanemaker.com with an radius of 65mm and 4mm for the base witdh/height. I used ledge interface and entered the lowest possible values, so when you are slicing your lithophane, you only get the round lithophane.
Depending on the height of your lithophane, I added several led holder files with the height they can be used for. If you want a different height for your lithophane, feel free to send a message/comment.
you need to add supports for bottom lithophane holder and led holder. angle 50 degrees and touching buildplate, no towers.
for bottom and upper, I recommend using a top/bottom thickenss of 1,2mm and a wall thickness of 1,2mm, so that no ligth will leak.
for the rest of the parts I recommend using enough walls so that you have a nice and sturdy part that will last for a long time.
