Prank 2x4 Building Block

This is a prank 2x4 building block. It is the same size as normal blocks except for the parts which snap into other ones. This makes it very difficult to tell apart from other blocks and impossible to snap them together! Mix a couple of these into your friends collection and watch him go crazy trying to fit it into other bricks! I would recommend printing this in PETG, as it holds shape the best, however I printed it in PLA and it works just fine.
