A bit of a solution looking for a problem to fix.
Oversized. Over powered fan.
OK, college project. I get it. Made a DIY dryer and trying to figure how to market it. School project. Better to have failures here and not in the real world.
I'm going to say you missed the up front R&D. Look at existing solutions, what problems exist with those? Can they be improved? This doesn't look friendly to ship. Pretty sure the design didn't have that much evolution to it. V1.2, no realizing there was a fundamental flaw and starting with a V2.0
I have a similar DIY version. Separate legs that are dropped into the suit first. So much less fussy than the video of threading the legs onto the slingshot. Height looks to be an issue, I bet that is over 8' tall. Lot of homes don't have the ceiling height for that.
