Description
I wasn't satisfied with the other 3D printable designs out there for a 120mm PC fan based soldering station fume extractor fan. I felt they'd take too long to print and/or use too much plastic. Thus, I decided to leverage some of the structural rigidity tricks I've come up with when using vase mode printing to meet my criteria.
The extractor is close to the worktable because that's where most of my soldering happens. I used a light-up LED fan because more light is better for seeing what I'm soldering. As well, that's a detachable grill on the back to hold in an activated carbon filter pad.
The front cowl of the fume extractor is the only part that printed in vase mode, and even with vase mode you'll notice that it actually as an ‘inner’ and an ‘outer’ surface. The secret sauce is a 0.1mm gap/slot all the way through the print that makes the ‘inner’ and ‘outer’ surfaces actually only one surface. And by varying the gap between the ‘inner’ and ‘outer’ pesudo-surfaces to the point of the two surfaces fusing together when too close - rigidity can be increased like corrugated cardboard.
