120mm PC fan ducts/risers

I recently saw some of these on TikTok and have not found any files like them. I designed these myself, from the ground up. That being said, I AM NOT A PREOFESSIONAL, nor am i great with CAD lol. Feel free to make comments, ask questions, ask for other variations, share your print profiles, and give me notes please. Thanks for downloading and happy 3D printing! Disclaimer: 1.) You WILL need LONGER PC fan screws or RUBBER PC fan mounts.2.) Some of the mount holes will not take screws AT ALL due to the angles. (again, i suggest the rubber fan mounts)3.) some of these are going to be VERY case specific.
