This is Thing-a-Week #5, previous things can be found here. http://www.iheartrobotics.com/search/label/thing-a-week
Currently this is untested and experimental due to the holiday weekend and since it is still printing.
These parts are used to build a positive pressure glove box style clean room.
The goal is to produce somewhere around a Class 10,000 cleanroom environment in a small space that is useful for taking things like hard drives, cameras and lasers apart.
The current design uses a shopvac air filter part #VF3500, but part #VF6000 is probably preferred.
Based on initial estimates the RadioShack Cooling Fan part #273-0241 should provide reasonable performance when matched with the air filter, however testing has not yet been completed.
Connecting rods are cut from 6061-T6 Round Aluminum tubing, and tapped M4.
OD 0.25" Wall Thickness 0.065"
The open endcap connects to the fan using M3 countersunk screws and nuts.
The design may require caulk or gaskets to function properly.
Print and assemble according to the exploded view diagram.
Cut and tap connecting rods to length. Use a file to trim the length of the rods to ensure a tight fit.
