I was watching a You Tube video by Toys in the Attic about modding the Monoprice Select Mini. I liked the fan guard he was using and contacted him to see if he still had the files. He couldn't find them. I decided to make my own. I took a screen shot from his video and converted the "V6" to a .stl file. I added it to a fan guard by Pyrex238. I use a Noctua 40mm fan that has M5 screw holes. The screw holes on the guard were too small so I drilled them out to 4mm.
