This is a simple lightbox made into the JWST mirror shape with a backlit print illuminated by LEDs. Everything can be printed with no supports. Use about 15% infill for strength and easy top bridging. Keep it at 100% size or things wont fit. It is around 30"x28" when finished.

You will need to print:
(5) Sides
(1) Plug side
(6) Tops
(1) Nasa Hex

You will need to purchase:
(2) pieces of 0.093"/2.4mm acrylic/plexiglass at least 32"x32" (or one large one you can cut
to make 2) https://www.homedepot.com/p/OPTIX-36-in-x-72-in-x-093-in-Acrylic-Sheet-
MC-10/202038046
(1) piece of 1/2" plywood, at least 32"x32". Any thickness will do, 1/2" is a good middle
ground for strength and weight. This is for the back.
(1) LED 16ft light strip with remote. Most of the brands are the same thing, so the plug
should fit into the 3dprinted "Plug-Side" piece.

(1) Backlit print. The print needs to be a really high quality image printed onto "Backlit Film".
I get mine from PosterPrintShop.com. The shape needs to be printed at 29.5" x 27.5",
this will give you just enough extra to trim to fit. Use any images you want, here is the one

Rough instructions:
Print all the pieces and superglue them together to form the side ring and the top ring. You can use them to trace the shape needed for the plywood back and acrylic sheets that you need to cut next with a jigsaw. The image goes between the 2 pieces of acrylic, and the acrylic fits onto the lip on the side pieces.. Place the LED string along the inside sides making two full loops, make sure to start with the plug inserted into the "plug side" piece. After everything is fitted, finish with the top ring and secure it with 6 small screws. Place the NASA hex on with double sided tape.
