Dustbuster vacuum adapter

thingiverse

This is a custom vacuum adapter for a Black and Decker Dustbuster, model number NV7210N. I designed it to make removing air from zip lock style bags easier. My main use case is long-term storage of filament in rigid.ink zip lock bags. To help the dehumidifier packets keep moisture content low, I wanted to remove as much air as possible. This is just my first version, and while it works okay, I plan to release a v2 with a longer tube that tapers at the end. The boss will also be elongated for better usability. The current design is pretty flimsy, but I'll work on improving it in future versions.

The new design includes draft angles on the internal boss to improve rigidity and a draft angle on the spigot to make it easier to use. The spigot and boss are both longer, making it simpler to insert the spigot into the corner of the zip lock bag rather than the center seam. [](https://youtu.be/53n0HizPsj8 "YouTube Video")
