Yet another Mario Question Mark Block. I designed it very sturdy, because I want to use four cubes as feet for my TV.
Its dimension is 10 cm x 10 cm x 10 cm.

Easy to assemble and glue.

It's a multi part model. Two times three parts for the cube itself and eight parts for the question marks. So you need to print the identical bottom/top, side 1 and side 2 parts two times respectively. And of course four question marks. 

Works also great in 50 % scale as shown in the pictures.
