Flange for stepper driver fan duct with chipset vent

thingiverse

This design is specifically created for the flange. To access the cooling duct, navigate to the part located below. I was looking to install a fan from https://www.thingiverse.com/thing:3796022, which is designed to cool TMC2208 stepper driver radiators. My mistake was not checking the mounting specifications of the fan I purchased beforehand. To save some money, I chose a Gelid Solutions Silent 40mm fan instead. The flange fits snugly into the mounting holes, and if it's a bit loose, you can secure it with some glue - unfortunately, I didn't. You may also want to try printing it in TPU, but I haven't tested that yet. Mounting holes are designed for M3-sized self-tapping screws. For this fan, I used 12mm screws. You will need to reattach the wires after assembly. Once everything is screwed into place, the bottom plate fits perfectly, and all eight mounting screws can be utilized.
