This is a clamp to make the Lillabo train bridge set stay together better.

Just print two of these and put over the wooden bridge supports and your kid will have to enter Godzilla mode to tear it down.

The wood supports are supposed to be 65mm wide but I noticed a small variation on the orientation on one of my supports so if it doesn't fit perfect, just flip it 90 degrees.

v1 has sharp corners as pictured.
v1.1 has rounded corners
