Summary

It is impossible to use the Ryobi Stick Vacuum on carpet. I designed this riser which allows it.
December 31st - V2 uploaded. It contains extra supports and 1mm triangular clips to help it stay in place.
*If you find that your vacuum is riding too high, just print it again but sink the model down 1mm or 1.5mm below the build plate on your slicer. Your slicer should print only what remains above the build plate. Removing 1mm worked well for me and allows the brush to work effectively on my thin carpets.
