Air Vent Redirector
thingiverse
Backstory is that my office has an airvent directly at my feet and they get super cold when the AC runs, this is both a footrest, and a means of keeping my feet at a reasonable temp. Would recommend printing with 2+ perimeters, otherwise low infill works just fine for this. Due to the size of the object, needed to split it into two to fit on most build plates. Supports should not be needed, the only sharp overhang has a built in support. I bound mine together with some fabric tape down the seam with no issues.
