3D printed flow hood prefilter mounts * 1
    #27097511 - 12/19/20 11:10 AM (3 years, 1 month ago)

I love working with agar but really hate working in a SAB, so I decided to build myself a flow hood. I only have a 24" depth countertop to work with. Most hood builds I see are at least 16" deep, which wouldn't give me enough room to work in front of it. I settled on doing one 12" deep which gives just enough room in the plenum for the blower opening and still gives me enough room to work. I've read some different opinions on the optimum plenum depth. The general consensus is that it should be deeper than what I have, but it seems to be working pretty well so far. I let a plate sit open in front of it on Wednesday when I finished the build and so far there are no signs of anything growing on it.

With the shorter overall depth, I didn't have enough room to build a prefilter box around the blower. I'm using a knockoff version of the Dayton 1TDT8 which is just shy of 12" from front to back. I enjoy 3D printing things and like to incorporate it into all of my other hobbies, so it seemed like a perfect opportunity to design something that bolted directly onto the blower to hold a regular HVAC filter. This blower has openings on both sides. The completely open side was pretty straight forward, but the other side is where the motor mounts and was a bit trickier to design.

Final product



For now I only have the mounts directly bolted on the motor, but I plan on putting a bead of silicone between them to prevent any air from bypassing the prefilter.

Hope you enjoyed looking at it. If anyone is interested in making this, let me know and I'll post the STL files to Thingiverse.
