This is a very simple and useful lithophane print holder with tea light candle stand.
I made my lithophane at the website http://3dp.rocks/lithophane/

The holes fit a standard tealight candle (4cm diameter), or you can use battery powered ones if they are bright enough.
Do not try to print this in PLA if using actual candles, the heat from the candle (especially as it burns down) will warp the PLA as its in direct contact with the metal shell of the tealight itself. Polycarbonate, ASA & ABS are all known to work and not deform. I believe PETG may be safe too, but its right on the edge.
