PTFE Lid for drybox

Hello,

I made this part to improve the drybox that I made. 

This part is designed to pull the filament with and to close a PTFE tube from the drybox. This allow to pull the filament without to open the lid of the drybox, limiting the humidity to go in. 

Made for 1.75mm filament at the begining. But could work on different diameter due to the conic cut shape. 

Curious to have any comments or suggestion in order to improve it again ! 

Happy printing,
