This is a drop through long board wall that works with command strips. You should print two, one for the bottom and one for the top. When attaching to your wall make sure long board is resting on both the top and bottom mounts to ensure the command strips can hold it. You will need one m3x25 bolt for the latch. I printed it in PETG with 20% infill and then spray painted them. They work well with my loaded dervish sama board. The mount is 18mm wide and 40mm long and 32mm deep where it goes through the deck. The back plate is 80mm sq. Hope you enjoy it.
