Koprov's original linker was great, but didn't quite “snap into place”. The V2 requires screws to lock into place, and I wanted to be able to put the connector in from behind so it's not as obvious.
I printed this in PETG at .2mm height, so the lip at the front is only a few layers. This allowed it to bend just enough that it friction fits at the end of the peg when pushed in. I don't know if this deformation will work with something brittle like PLA.
The author remixed this model.
Updated Korpov's model to extend out to the full 5.86mm width of the boards, and added a lip to the end of the pegs. Now it actually “snaps” into place.
Also added chamfers to the edges for a cleaner look/feel.
