Using a 24" x 24" x 48" indoor grow tent. It's perfect for the application, designed so you can control the lighting, heating, and ventilation really easily. I used to use a photo tent for just the FDM printer, but I plan on getting a resin printer so I needed to expand while keeping the fumes under control. Hopefully the inline fan plus respirator/goggles/gloves combo will be just enough, but there's always just brute forcing it with a giant fan on the outside.
Sadly I can't link either, because they are no longer available.
This is the larger of the one I got, but same company: https://smile.amazon.com/Reflective-Hydroponic-Observation-Waterproof-Growing-2x2/dp/B07L936KS6?ref_=ast_sto_dp&th=1&psc=1
I'm looking into one of these or similar. Planning on a digital temp controller with a heat mat because the printer likes it a lot warmer than I do.
