Hacky-Sack Airless/Beanless

Airless or Beanless Hacky-Sack.  --TPU - Med-Hard. 

Version 2: hack.obj hack.3mf.  I will keep the old hackeysack.3mf up.  If Someone would not mind printing in in tpu and giving the old version a try and test run with TPU that would be awesome.  I printed it in PLA and it was too thin and brittle to remove from the plate without pulling out the bottom. But it was so light and interesting looking I figured I would just leave it up and someone may find a use for it. 

I was at university for a lifetime - and during one of my artistic stints I was majoring in Theatre at UMD.  Mostly Tech Stuff.  A crew of us played hack on a daily basis during breaks in the mezzanine and outside near the Jacques Lipchitz sculpture (allow yourself a Beavis and Butthead Moment with that name) .  So today my son was watching a youtube video with some dude who had ordered a $1000 airless basketball (redonculous) and I was like “We should make a hack” an “Airless Hack”  which is dumb… becuase they never had air… but Beanless… just sounds – unfinished… so Lets go with Airless Hack.
