Download the 3-D print file for the rocking base of the board. You may request one by email, or by filling out the form to the right.
Print two copies of the base. Because the part will need decent compressive strength, I've only tested high infill prints (60% or higher, and 2 shells), so I can't recommend anything lower.
Why am I requesting your email address? I want the whole Explode the Controller Project to be available for everyone, but I also want to connect with other STEAM educators and build my professional network. No spam or sharing your info, I promise!

Mix up some cement mortar- I used this stuff, but most any cement product that pours easily should work. Fill each of the bases level to the top with the cement mortar, making sure to press it into all the crevices with a thin stick as you go. Scrape any excess cement off to keep it flush with the top of the printed base. Allow 36 hours to cure.
Cut a 20" x 20" square of 0.5" thick plywood. Attach the each filled, printed bases along the center line using 8, 0.5" flat head, wood screws. Be careful not to over-tighten the screws (you don't want to crack the plastic or punch through the plywood).
Attach a Micro:Bit to the board, and start rocking!
