About this 3D model

The objective is simple: Assemble a perfect square with all these pieces included and without empty spaces. For now I didn't put the solution here because I don't think it's a very difficult challenge and I don't want to spoil the fun. :) It is a fun challenge to try with your friends (try giving them only a couple minutes to solve it). Have fun and leave your comment. Thank you. You can help me buy a beer! :)Any amount would make me happy and extremely grateful.
