Base for holding acrylic panels up for a customized LED diffused night light. Two parts, set the print orientation for no supports, 0.2mm layer height, 15% infill, polyterra PLA, etc., etc.
For the panels I used 2.7mm cast acrylic (https://www.amazon.com/gp/product/B09FHYDGM1) which were cut into 97mm x 97mm squares and laser etched with different designs.
For the LEDs, I used a white strip 5V (https://www.amazon.com/gp/product/B08M65DKZ7) which I cut into 6 LED segments (one roll is enough to make more than twelve) and then were fitted onto these connectors (https://www.amazon.com/gp/product/B01MY7K8IT) which don't require any soldering. Just peel the backing off the LED strip and stick them onto the 3D prints.
