Hoop Glider - Adjustable

This design has minimal plastic use and is a slide together model.

I made it from PETG to make it a little more durable (you do throw it after all).

Layer height is 0.3mm, 0.4mm nozzle will give you one perimeter for the hoops.  I used a 10% infill.

There are little nubs on the body to loosely lock the rings in place.  HOWEVER, you can still slide the front ring backwards along the body in an attempt to achieve the optimal gliding performance.  Makes for a simple science experiment.
