This is a basic brick style Mario block.

There are two versions one with that is a solid block and one that has a cylindrical void in it to store things..

The model is large and prints without supports on both versions. It measures as a 90mm cube. It can be scaled down without any issues. I have printed it down to 33% or 30mm without issue.

Perfect for making building blocks for the little ones. Or just neat desk items.
