Great work, I still don't have a 3d printer but plan to purchase and build a Prusa MK3. I refuse to begin my printing journey without an enclosure using a HEPA/Charcoal filter, because I live in a one bedroom apt. I know after we send the $10 we get the specs etc, but I was wondering just about how much money this has run others sourcing parts in the US? Anyone have any general estimate? I mean for everything: filters, electronics, and all. Obviously will need a rasberry pi, displays, lights, thermometers etc. The Prusa is going to seriously set me back, not cheap.
