Dây Gãi Lưng “Back Strap Billie” (Scratcher)

I loved this kind of scratcher. I got one in Europe, many years ago, that was build with a long bristle brush. Worked so well I wanted to see if I could replicate it for this contest. Why waste time on a single spot when you can do large areas all at once. 

You will need to print one of each handle and 4-6 of either the Medium or Extreme 9x5 fabric depending on the length you need. Each section is roughly 7”. I used 5 for my personal one. 

I printed the parts with 3 walls and 15% infill. If your slicer has options for inclusion and exclusion, choose exclusion. that will make everything loose enough to move smoothly. 

All parts fit a 220x220mm Build Plate.

They all snap together with a bit of force and won't come apart very easily.
