You ever get one of those itchy spots just under your shoulder blade you can't quite reach? And have a long boring zoom meeting, and some fair to middling 3D modeling skills... And a printer right behind you doing nothing?
I know, right? All the time...
This is a three part model, to make a long back scratcher for those times when you just can't reach. The join piece is deliberately very snug, so if it doesn't quite fit due to different printer settings, you can go up or down 1% scaling to get it to fit. Or print it loose and glue it together. Mine is friction fit and is not going anywhere.
I scaled mine to fit on my Prusa print bed, but if that's too large just scale all the pieces together to fit your bed, should still work.
