This was a quick 1 (ie 2) day build, based on http://amasci.com/amateur/hovercft.html.
We used a Ryobi corded leaf blower that was for sale at Home Depot.
Paul JF designed an adapter for the leaf blower that we printed in PET-G. Worked really well.
It is capable of lifting both kids and adults!
We tried using a second leaf blower as propulsion, but it turns out you need much more air-flow to move than you do to set up the air-cushion.
It’s now part of the MakeItZone collection of cool contraptions!
