Xtool F2 Rear Fan Filter

Add a HEPA Charcoal filter to the back of your Xtool F2! This may also work for other F-series laser engravers but I don't have any others to test with.

This is designed to use the following HEPA Charcoal filter: https://www.amazon.com/dp/B0BJB8BV89

The tolerance is designed to be air-tight so you will really have to wedge the filter in and onto the rear fan of the machine. If you have trouble, scale the model up by 0.1-0.5% to give more clearance.
