Spin Trainer for Roller Skaters and Ice Skaters

This is designed specifically for me to use as a training aid for learning 1 foot spins on roller skates. You put it on the floor, put your foot on it, push off, try to spin. Loose balance, feel dizzy and repeat.

I printed mine with 100% infill in PETG it weighs 200g. I sanded it a bit, but that's cosmetic, and not necessary.

The original CAD model is Solidworks modelled by me.

It's inspired by the spin trainers that Edea make, although I've never actually used one of those.

2 versions:

“SpinTrainer_v5” has the spin point close to the ball of the foot, this is simulating spinning on the 2 toe wheels of a roller skate.

The second version “SpinTrain_MID_v5” has the spin point further back in the middle of the foot. I think this is more like an ice skate, I've not made this one, but it would be more suitable for ice skaters.
