All the same details of the previous v2 revision apply here. We just have some slight tweaks for allowing magnetic features.

I use tree supports only touching the build plate.

There are two “sets” files. The “Two Panel Set” includes everything you need for 2 panels outside of the shortcut and insert pieces. I made this so that if you want a tri-colored board, you can easily print one color after another. Similar set up with the “Three Panel Set” but would just need to be printed twice if you wanted a 6 person board.
