Recently bought a Xiaomi Mi mini handheld vaccum cleaner. Besides having a little vaccum cleaner on board of our small camper it can also be used to deflate the plastic bags when I store my filament rolls.
I created my own nozzles, which can be mounted on the vaccum cleaner itself or on the extension tube.
For easier print I included a thin ring of support (only 0.4mm thick) which can be peeled off easily.(All three models available with and without support)
Update 2020-08-27: Added a new version of the deflating nozzle, which has a bit wider hole to allow faster and easier extraction of air from sealed bags. With the old version the vacuum cleaner sometimes "complained" that it could not pull enough air and switched itself off.
Update 2022-09-11 Uploaded a version 3 of all nozzle with slightly modified socket for better fit. Only marginal change, but now they sit firmly on the Xiaomi Mi without slackness.
And I added a "desk cleaner" (an extra flat nozzle) which can be used on (usually non-empty) surfaces like desks or workbenches and will pick up dust only as most other stuff potentially lying around will not fit into the only 2mm wide openings and will not be sucked in. (I have such a nozzle in use with my normal household vacuum cleaner for a wile and it turned out to be very useful - will probably publish that, too)
Update 2023-11-05 Uploaded a blower nozzle for the bottom of the Xiaomi MI as requested (see comments). This might be published later as a separate model
