Flat Mount Hygro Holder

Took the screw mechanism from the original (thanks for that!) and created a mount designed for sticking a hygro inside a filament tupperware container. The hygro's have a slightly annoying bevel on the surface, so trying to mount with tape inside a tub didn't work very well: one came off within half an hour of mounting. Instead, this holder provides a nice big flat surface for the mounting tape. Designed for Gorilla brand 26mm wide tape. First one printed fine: now printing another four :)
