Get her to a kids gym, they’ll teach her how to land safely at least. I haven’t done gymnastics for 30 years but when i go for a sixer i still auto roll to minimise injury.

btw, where are you at? There’s going to be a few test prints, so a city would be useful.

…yeah not all printers are prusa.

(says the woman who wouldn’t piss on an ender if it were on fire lol)

Have a look at stlfinder, thingiverse or cults3d. Someone has very likely already modelled and created one free to download you can take anywhere you can get 3d printing done.
