Filament Vacuum pump head / adapter

Hey!

Do you have a vacuum pump for your filament?

Did you lost the adapter or head?

or maybe the seller didn't include it in the packaging… (that happened to me)

So, I decided to model one! and I added a cut out to print a sealing ring in TPU so it helps when extracting the air.

Notes

• The first version of this model, which is not uploaded, was to loose where it inserts into the pump so I put teflon tape to help sealing.  I hope this version fits better, but anyway if you feel like the pump is leaking air between the adapter insert and the pump try putting some teflon tape.
• Most of the times the air is not coming out from the bag it is either the pump is slow or the pump is not correctly position around the valve. Keep that in mind!
