Fluidstance EXTREME difficulty challenge cap

Fluidstance makes a challenge cap which increases the difficulty of their standing desk balance board. This is somehow still too easy so I made a bunch of even more difficult versions and a fully paramaterized fusion model as well which enables you change the height (difficulty) of the model. 65 is pretty much the maximum however. Be careful with these, I'm not responsible if you fall. Update: ASA holds up for a bit but I've since reprinted in PET-CF for longer term use which really holds up well and feels much more sturdy.
