M7 Max Exhaust Fan + Reductions

I made this exhaust port for the M7 Max with a reduction so that everyone can attach any hose they want for the ventilation system of the printer or their enclosure.

In the gallery there is a .gif that shows the assembly.

There are 3 reductions: 40-70, 40-62 and 40-92. If there is any interest i'll post the step for them so everybody can modify their own.

I've used M4 bolts and the fan used is from aliexpress: https://www.aliexpress.com/item/1005005641181053.html?spm=a2g0o.order_list.order_list_main.39.68401802ZIJr8z (the 4 inch one).

I'm also working on a smaller version for those that don't have so much space in the back so stay tuned.
