This is a coffin I made with PLA and glow in the dark. I paused the print and changed the filament to glow in the dark. I use it to hold candy on my desk at work.

No support required. I have two different files. Coffin Lid and Coffin Bottom. Lid and bottom 1 are bigger models and will require a larger 3d printer. Lid and Bottom 2 were scaled down to fit the bambulab x1.
