120mm Fan Mount System

thingiverse

This is a **120mm computer fan mounting system**. I've included a remix of [120mm Hex fan grill by imKieva](https://www.thingiverse.com/thing:1595208) with some simple locator tabs, but honestly you can use just about any grill out there so long as it is approximately the same thickness (or thinner). The flexiblity comes from the fact that the mount base is threaded to take multiple different mount options. I've included one for a standard 1/4-20 thread; which, is universal for camera equipment including tripods. I'm working on a GoPro mount and Ram ball mount that will simply screw into the base. I'll also probably create one for the printable "gorilla" arm systems out there. The mount works just fine with standard self-tapping computer fan mount screws like [these from Amazon](https://www.amazon.com/Easycargo-Computer-Screws-120mm-Cooling/dp/B07VLHBL5Q/ref=sr_1_3?crid=23XVD1J70139S&keywords=computer+fan+mounting+screws&qid=1654096580&sprefix=computer+fan+mounting+screws%2Caps%2C46&sr=8-3). In case you don't have any, I've included printable nuts and bolts that will do the trick. Note that the bolts are a tight fit, and I'll probably shave 0.1mm off them at some point. Also, have a care not to cross thread the tiny nuts and bolts... same for when screwing the mount into the base. Print all as shown in the diagrams. No supports needed with the show orientation. Print the nuts and bolts at your finest printable resolution with brims. The base was printed at a std. resolution of 0.2mm, but could probably benefit from something finer. The screw in mount was printed at my printer's best fine resolution. Infill for the nuts and bolts should be at least 80%. For the rest of the parts, it's up to you, but I'd go with 20%+. For the base you may want more like 40%+. Infill pattern is your choice. I've included the full Fusion 360 modelling file, so if you want to mod it, you don't have to do the stupid import of STL files. Let me know if you create something cool or make a significant improvement.
