I'd like to use your template standard but create my own lithophanes to go in the frame. Do you have any recommendation on the size and depth for the lithos? Thanks much.
I measured the inside of the frame using 3D Builder's measure tool. The inside of the frame said it was 105mm W x 135mm H. So, I'm currently printing with that measurement. I'll let you know if it worked. (I'm printing the frame without the diffuser as well)
I sadly didn't have enough filament for 4 panels with motives for my lamp so I decided to print this blank version in black to block the light on the back of the lamp altogether. Works well enough :)
