Shower concept

A back scratcher for the shower & bed were highly desired.  Some ability to wash it was highly desired.  The mane problem with the shower was making it waterproof.  There were ideas for commercial nylon farsteners.  Nylon bolts have to be mail ordered & are expensive.  The smallest nylon farsteners locally are 1/4" so they could be more easily printed.

There was growing dissatisfaction with the way the bolts always came loose.  The leading idea was a 3D printed farstener & even better, a snap fitting.  In reality, it might be cheap enough just to permanently glue the scratcher on the handle.

Bed concept

Using it in bed has proven difficult but desirable.  The mane problem is storing it where it won't get smashed & grabbing it without getting up.  The leading idea is to cover up the scratching head.  The handle could fold up, with the scratching head going into an enclosure.  The scratcher & enclosure could be separate.  That might be easiest.
