Balance Board Bottom Bob

Stand up desks are all the rage at my office these days, and a balance board one of my coworkers brought has been a big hit, too! Everyone (including me) takes turns balancing on it, and when I took a look at the bottom, I knew it was my next 3D printing project! I call it the "bottom bob" thingy...

Designed in Fusion 360, printed at 40% infill in PLA, it took nearly 7 hours to print when using Honeycomb infill. I've since then tuned my printing speed and infill (using Cubic) and got it down to 4 hours.

The board itself is a Laminated Pine Round (17.75" x 1") I found at Home Depot for $6. I used #6 x 3/4" wood screws to attach the bottom bob to the board.

Testing continues, while I figure out if this thing can withstand my weight (230 lbs), but so far, it seems to be working well and it's very sturdy (and heavy!) at 40
