My son loves minecraft and got into modding it, we enjoy doing battles with lucky blocks, astral lucky blocks etc.. he asked me to create a block so here it is!

It is about 60mm x 60mm x 60mm. Scale as you wish.

the design isn't perfect, it WILL require glue, the "middle" piece needs to be glued to bottom of the lid. I might redesign the lid later to have an integrated skirt that fits into the bottom part, but for now it is what it is.. at least with glue/sanding you can get the fitment how you wish which sometimes is better anyway.

It printed fine without supports on my ender 3.
