PolyBox tube bracket

Bought a PolyBox, this is a very nice box that keeps the filament dry and clean.
So I needed a bracket to fix the tube that guides the filament to the extruder.

Changed to work in progress: the bracket is not strong enough, designing a new one.

PolyBox_tube_bracket.stl is the final design. I used the hole that is already there to fix the bracket with a small steel nail. Now it is more easy to remove. This is for a future mod when i will place the PolyBox in the cabinet below the table.
