A plain tissue box with bottom lid to paint and decorate to your liking.
Internal dimensions are 115x101x122mm (LxWxH). There are three versions, "sharp" has 90° edges, "chamfer" has chamfered edges on top and the side and "fillet" has rounded edges on the side and chamfered edges on top.
Can be printed without supports
Printing this is super easy, as long as your first layer works you shouldn't have trouble.
0.2mm Layer hight and 10% rectilinear infill worked fine for me.
