So my Flextail airpump kicked the bucket (died) a week before a backpacking trip, wasn't in the mood for sketchy lipo rescue and don't have enough time to order another one, yay!. So I printed this to dig myself out of a hole and inadvertently saved some pack weight 😅
BoM
- One 3D printed nozzle
- One 30L garbage bag (~ 8 gal)
- Some electrical tape
Tools
- 3D printer of your choice
- Scissors (for clean cut of the tape and cutting hole in baggie)
- Hobby knife (""exacto knife"") for clean up
3D Printing instructions/information
- 0.4mm nozzle
- 3mm layers
- 3.5mm first layer
- 3 vertical shells
- 0.35mm Extrusion width
- Basically tinker with your extrusion width and shells so you get 3-5 perimeter layers for optimal stregth
- I printed mine with PLA, but you may choose other plastics.
Assembly
- Grab your garbage bag and grab a 5 mm (~1/4 of an inch) bit of the bag and cut it off, you should get a hole thats around 25 mm in diameter (1 inch)
- Put the nozzle in with the lip on the inside of the bag
- Use the electricians tape to affix the nozzle to the bag and seal it
Note: Use the tape sparingly to keep weight to a minimum - Ensure there are no sharp/rough edges, if you are using a garbage bag, the slightest of roughness will likely tear the bag
