Description
I designed a full-size 3D-printable baseball bat. I used an M8 threaded rod inside to make it stronger, and it worked 🤩. I’ve already tested it with some 3D-printed TPU balls, and I think it will also work with tennis balls. With the hardware inside, the bat weighs around 900 grams and feels solid in the hands.
