Lego Piece

This is a 3D printed Lego piece. It works well with regular Lego pieces. It has full clutch power both on the top and bottom, and it is able to firmly clutches onto other Lego pieces at any positions. However, it is somehow hard to take off from other Lego pieces because it has an over-strong clutch power.
To be careful when using it, since it has a very thin top that makes it fragile and easy to break when violently treated.
