DIY Balance Board Base

Wanted a stand up balance board to go along with my stand up desk, but didn't want to spend $50+ for one. Cut out the platform from some scrap wood I had. Cut the top blue pad out from an old yoga mat. Then all I needed was the balance ball portion on the bottom so printed it.

Two versions. One is slightly shorter and has a larger flat so easier to balance on. If you want something a little more difficult than print the other one because it's slightly taller with a smaller flat so it's more tippy and harder to balance on.
