Vertical base for Comfort Zone window fan

thingiverse

I bought a Comfort Zone twin window fan to use vertically, but its edges were unstable. Designed these brackets to fit into the existing grooves and keep it upright. There's a left and right version which are just mirrors of each other. I printed on my Ender 3 using PLA, 0.3 layer height, and about 50% infill. No need to remove the supports if you print everything vertically. Happy to send the .STEP files for anyone who wants to customize; this was made with a bracket width equal to my windowsill.
