A logical tile for the 3D-Printable board game Hextraction which has an explicit lock. If any balls find their way into the lock, the main straight path will be completely impassable. The tile allows for three different orientations and the lock works correctly in all three.

Tested and working with both 10mm balls and 3/8" balls.
