I've made a cute shadow box from Basic PLA for valentine's day with various designs for the couples. Choose which couple you like most and put a total of 6 inserts (textured side facing down) into "case_front". They have numbers from 001-006 on the build plates, and should easily slide down into the casing.

Depending on which lights you want to use, USB or battery powered you can put fairy lights through the hole of "case_back" and fix them with some tape or use the pegs that are around the hole to form a circle. Check the photos for details. Fix the battery box with double sided tape into it's place. I bought a 3 meter fairy light (warmwhite) that uses 3x AA batteries so they last way longer than the version with the button cells. For the Amazon link to the warmwhite or RGB fairy lights - scroll all the way down.

UPDATE 2024-03-27: created a collection with all my available inserts for the shadowbox. They can be combined with each other https://makerworld.com/en/@technerd/collections/962148

UPDATE 2024-02-12: included STEP files for “007_diy_empty_insert” and "case_back_003_RGB_fairy_lights" if you want to create your own inserts in Fusion360 or change the backplate to fit your own lights.

UPDATE 2024-02-02: new “case_back_003_RGB_fairy_lights.stl” now compatible with both models 3m/10ft & 5m/16ft RGB fairy lights - I made the pegs longer & bigger circle diameter to fit the bigger battery box from RGB lights.

UPDATE: Btw. you can also use RGB fairy lights - here is what they look like in different colors:

Print the "case_cap" 2x and slide them over the front and back of the heart. They're press fit and should stay in place, if not use some drops of glue or double sided tape. The overall size of the box is 215mm x 215mm.

For perfect results make sure to use the golden textured PEI plate and calibrate your filament.

I will try to add new inserts for the box from time to time. Just check my profile or my collections for new uploads like the new castle Neuschwanstein inserts. Until now these are the included designs here. Happy printing!

Btw. these are the fairy lights (warmwhite) that I got from amazon. Size of the battery box is 74mm x 51mm x 19mm. It has an integrated timer and stays on for 8 hours, so the 3x AA batteries should last 1-2 months: Amazon Fairy Lights

The new “case_back_003_RGB_fairy_lights” is compatible with both models RGB and warmwhite!
