This is a lightbox made from an image chosen by a raffle winner at a local SEND school.

It just about fits on to H2D print bed and needs 2 AMSs to get all of the colours.

I used a female USB C mount to get power

RUNCCI-YUN 6PCS USB-C Pigtail Cable Extension - Waterproof, Panel Mount, 3A Charger : Amazon.co.uk: Computers & Accessories

This press fits into an 11mm negative cylinder on the back plate. (I haven't added this so you can choose the position for yourself)

Then soldered to strips of 5V LED strips.

This works better than putting the hole in the side and running the LED strip around the outside, as the light created a halo type effect due to the large size.
