Building Bricks (Multiple Kinds)

These are just random bricks I made using OnShape, I have tested the 1x2 Bricks and they work fine with real LEGOs and by themself. Please note that this Project is a work-in-progress and I will be changing things later on.

Edit No. 1: I made a new 1x2 Brick file with larger studs that might help it connect better, if it works I will change the rest of the bricks to that size (4.9mm to 5.1mm).
