LEGO coffin

basically I took Typhlosaurus' "Minifig-sized coffin", and added LEGO studs at the bottom so you can put your LEGO figurines inside.

NOTE: if you change the scale you will also need to change the stud distance/size (LEGO studs are 8mm apart on center, for further reference https://grabcad.com/tutorials/lego-01-basic-dimensions-bricks-explained)
