About this 3D model

This is Thing-a-Week #5, previous things can be found here. http://www.iheartrobotics.com/search/label/thing-a-weekCurrently 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.http://www.ridgid.com/Tools/Vac-Filters/EN/index.htmBased 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"http://www.onlinemetals.com/merchant.cfm?pid=6844&step=4&showunits=inches&id=71&top_cat=60The open endcap connects to the fan using M3 countersunk screws and nuts.The design may require caulk or gaskets to function properly.
