Ever wanted to cause destruction with your own blue shell? Well now you can!

The green, red and blue shells have haunted, harmed and humiliated Mario Kart players for years but now an architect named Michael Curry has posted instructions on Thingiverse on how you can make your own.

The shells have a remote control car as a base and the instructions inform you how to modify them so that they look like the shells, as seen below. Obviously you need certain skills to build them so not everyone can but it's great to see Mario Kart inspired modifications. If you do manage to make your own let us know in the comments section below.
