After using a some different Skadis boards, I realized that I didn't want to lose as many of the peg holes. I found the Infinite Skadis and adapted it to fit the side of the P1S with 2 of piece A and 2 of piece C. The connectors can be tricky to install, but I added in some CA glue for extra security.
