This model is best printed on its side or with the clip assembly at the top of the print. I advise against printing it flat, as when you insert it into the fan's foot slot it will split (unless you have adamantite layer adhesion lol). Avoid excessive supports around the clip assembly, as you will have to dig them out when the print is done. For strength, I recommend printing it solid.
Using PLA, print at 100% scale. I have not tested with any other filaments, but if someone tests them please let me know how it goes!
