Modular Crochet Board with Case

My wife asked me to print this Crochet Blocking Board by gevert.

I modified it to allow multiple boards to lock together with a connector piece to block bigger projects.
I also made a cutout for the connector piece in the bottom of the peg.
Finally, I designed a case to hold 4 boards that has a tray at the top to store the pegs.
