fan mount for 2020 aluminium extrusion

A simple mount for a pc fan to cool your prints, the distanse between holes is 82mm. and all holes are 4mm. in diameter. The print is very simple so that you can print it with a very basic printer, and it will help you get better more complex prints. Keep the fan off for the first layers, or you will have curling or delamination issues.

PS. Sorry for any spelling or grammar mistakes, I still have a lot english to learn.
