Hand Pump Nozzle for Version 2.0 Air Valve Vacuum Storage Bags

This is a manual hand vacuum adapter made of TPU that works well with my favorite type of filament vacuum bag.

I try to use vacuum seal bags to store the filament spools when not in use.

After sealing the spool with desiccant in the bag, I place it in its original cardboard box.

I've tried a handful of different bags and found that I really like the type that has a raised, low-profile, vacuum port in the corner. I've seen this type of port sometimes called the "Version 2.0 Air Valve"

These types of bags make for a quicker pump time than the ones with the purely flat/sticker type port but still allow the sealed bag to fit in the original cardboard box without bulging [unlike the bags with larger, screw on, center type ports].

The only problem I have is that the original hand vacuum's small green nozzle slips off the port as the bag constricts during pumping.

This model fixes that issue by replacing the hand vacuum's original nozzle with a flexible (TPU) one that fits around the diameter of the port.

The result is a firm fit for quick and easy sealing. I notice an improvement in number of strokes needed by the hand pump as well as less resistance as the bag gets tighter. It's efficient to the point I find it easier and faster to vacuum pump my bags by hand rather than using a portable electric pump. 

This nozzle does still work with the non-raised, sticker-type port bags but admittedly not as well as the original smaller nozzle. I don't really use those types of bags anymore but I keep the original nozzle around in case I have some legacy stock I want to use and reseal.

For my print: I used Overture High-Speed TPU Filament, with my Prusa Core One L HF0.4 nozzle printer set to the default balanced 0.20 Print Setting

Prints without support, 15% infill. Brim may help but was not necessary for my print.

I hope you find this print useful. I've included a .step and Fusion model in case anyone wishes to remix.
