M6 to M3 Converter Collar

This is a collar to center an M3 nut for use in a 6mm hole. I had a devil of a time finding a converter for an 80mm fan to a 4" dryer hose, then I found out that my SV08 didn't really have an 80mm fan. There was some kind of misprint or misadvertisement, or just Google AI being exactly as useful as we should expect it to be. So, not wanting to waste a pretty decent-sized print, I found a conversion from 80mm to 92mm fan. Measured the damn fan this time. Only I go to join the thing and the holes are big enough the M3 bolt that fits the fan converter and fan sail right through the hose converter hole. This is all pretty dumb, I'm sure. Anyway, not wanting to now have to waste two parts, I'm going to join the hose converter to the fan converter with some washers to keep them on, and these to center them in the holes. Recommend sizing down a little, just because I used the holes on the original fan part as kind of a boolean object, and it might be tight inside the slot. M3 should still fit okay. If you need a particular depth, don't be shy about scaling it on the Z-axis. The world's your oyster, baby, be a hero!
