Corner cat groomer - stick it to a wall corner and your cat will rub against it (or ignore it completely, it's a cat, they do whatever they want).
Update (11/20/2018): APPROVED by the cat!
Update (11/21/2018): Added a version that mounts on the wall instead of a corner.
Update (11/24/2018): Added versions with and without the cutout in the sacrificial wall (full_wall files have the wall go all around the model). SCAD is parametric, can produce either one.
The brush bristles are printed as bridges, similar to the "hairy" prints. There is a sacrificial wall around the entire print that supports the other end of the bridge. The SCAD file is included, everything is parametric: height, radius, bristle length. In addition to the geometries, layer height and line width need to be set to correctly generate the bridges. The STL includes the brim for the sacrificial wall.
Printing is long but not difficult. Postprocessing is tedious, you need to cut off the sacrificial wall. Use a sharp knife or scissors, and take your time (I broke a few bristles by rushing it). I printed the test object in PLA, but PETG should work better, less brittle and slightly flexible,
