Back scratcher

A simple, small back scratcher. This prints quickly, without supports. The brush is intentionally blunt, because thinner bristles broke off too easily. But it could be maybe sharpened a bit, if you need something that digs in a little more sharply.

EDIT 20-May-2023

Added 50mm to length! This fits on a Prusa MK3S+, diagonally. Barely.

EDIT 8-Sept-2023

I was able to add another 30mm to the length. Now it will really, really, barely fit my MK3S+. The next step would be to make it in 2 pieces but anyway this adds that crucial extra inch.

Back scratcher v. 2!!!
This new version has a bigger claw, to get around the spine's natural curvature.
Plus, an extender, for taller people. Because of your back's curvature, the extender may make it harder to get in a good scratch. I add a bit of a concave curve to both segments by heating it with a match on both sides for a few seconds, then gently bending the PLA. The alternative would be to print the model on its side with supports, but that's a lot of effort versus one match 😀.

To get the newer version and extension, download the V2 back scratcher and the extender.
