USB Vacuum Pump 50 kPa Holder for 1kg Filament Storage Bag

This holder for the common USB vacuum filament bag pump labelled with "50 kPa" is a base station for use with regular filament rolls.

It consists of 3 separate models, the base, the bottom and top part.
The vakuum pump goes between bottom and top part.

This is my updated Version - the tube parts allow now more clearance to the filament roll, also 4 of the bag zippers can be stored on the bottom part.

You can print them without any supports. 
Orientation for bottom and top part: upright.
Please use min 25% infill for the base.

Additionally needed for assembling:

6x M2 (min 6mm) screws (drill 6 top part holes with 2mm if you only want the thread in the bottom part)
2x M5 (max 20mm) flathead screws for the hinge
