Tissue Box Cover in the Style of Mario Question Mark Block. This is designed to go over a store bought tissue box so there's no bottom.
Files include a split question mark for easier printing. Print the Box and Question Marks separately and then glue them together.
There are also Complete versions for printing and painting or using a multi-material printer. The Complete files have full length 45 degree angles on the question marks to make it easier to print.
