WORK IN PROGRESS
This is an adapter designed to fit a blower fan and filter assembly to the following snorkel mask from Amazon (it may fit others): https://www.amazon.com/gp/product/B07YFPHJCJ
Here is the blower fan used: https://www.amazon.com/gp/product/B07RMJC9NT
The adapter, as is, provides a decent seal from the blower fan to the mask, and can provide cool, filtered air. (Print all parts in place, secure the filter mount to the fan, stretch a piece of filter material over the top, and secure it with the cap.
Outflow filtering is not yet implemented (that's next.)
The model is intended to be print-in-place, if your printer can handle ~60-degree overhangs.
To do:
- Add inflow filtration
- Add outflow filtration
- Add provision for batteries and controls/monitoring
- Test design
- Reduce overhangs to 45 degrees or less
Print Settings
Printer:
i3 clone
Rafts:
No
Supports:
No
Resolution:
0.24 or to taste
Infill:
30% or to taste
Filament:
Hatchbox or similar PLA
As desired
Notes:
Model should print without supports. The overhangs on the two outflow ports are a little steep, but they printed okay on my i3 clone.
You may need to have your slicer reverse a normal or two near the base -- I recommend previewing the print since the geometry of some of the curved surfaces is pushing the limits of what SketchUp can be trusted to do.Category: Other
