Filament Dry Box Add-on - Filament Port Cap / Plug / Cover

These are simple caps designed to seal off the open filament ports on this filament dry box (http://www.thingiverse.com/thing:961881). One has a central peg that seals to a 6mm hole which I drilled for my filament tubes and the other has no central peg which is a tighter fit. They both fit snug without any need for finishing with the settings I chose.
