Bridge over Tunnel

This is a bridge support designed to clip onto the top of Kest430's Tunnel (https://www.thingiverse.com/thing:4463367).

I'm still working on the best way to print it.
At the moment the best solution is to print it upside down with support blockers in place along the top of the "U" shape so that supports don't get generated on the part that clips onto the tunnel.


Note: This bridge support requires the tunnel linked to above.
