Telescopic Back Scratcher

thingiverse

This is a telescopic back scratcher that's really easy to use, just extend it to scratch and collapse it to store. When attaching the scratcher to the handle, never force it - if it feels tight, apply some lubricant to the threads first. Don't overtighten or you might end up stripping the screw off completely. I used PTFE lubricant before assembling the head onto the handle and it worked great.
