Monoprice Select Mini V2 Hotend mount 40mm fan and adjustable radial cooling fan

thingiverse

My stock hotend cooling fan started making a lot of noise, and I was looking for an adjustable height/removable part cooling fan. So, I created this one. The adjustable height might be overkill and adds weight, but it works. The main parts are printed in ABS for heat resistance, and the mounting pins are made from TPE. Printing with TPE on my Mini Select was a challenge - lots of glue stick, slow speeds, and patience were required to get usable ones. Inspired by other designs, I used two things as references: https://www.thingiverse.com/thing:2722203 and https://www.thingiverse.com/thing:2745732. I bought these fans for this project: Noctua NF-A4x20 FLX (https://noctua.at/en/nf-a4x20-flx, https://www.amazon.com/gp/product/B072JK9GX6) and a 5015 radial fan (50x15mm) from Amazon (https://www.amazon.com/gp/product/B07R4TGMK3). Some notes on the design: I used the Noctua NF-A4x10 FLX model in Fusion 360, but the pins are designed for the 20mm deep version. The dial no longer corresponds to anything since there is no slope hitting a switch 90 degrees from the part. I just left it as is.
