This is the conectablok! 

Supports optional. PLA is fine. 

Thanks if you print it. 

Game: try to stack as many as you can, without them falling over! If you achieve that, you can try and create as many interesting things and shapes as you can! In other words, use them to connect and make shapes and then stack them to see how high you get!

Base set is 8 blocks, set STL to desired percent. I used 330%. 

FILES:

Do not print prototype version 1 unless you want very very tight clearances. Prototype 2 is the current version, but I expect there will be things to fix. 

Don't forget - post your makes! It really helps.
