I converted the closet to a 3D Printing area, adding a bathroom-style ceiling vent fan and shelf to hold the 3D printer, resin, cleaner and accessories.

I will tell you I can't smell anything with the doors shut, and the vent does a good job of removing the smell during printing.

Can't recommend TeachingTech's "Resin 3D printing beginners step by step guide" enough, that was basically the model I followed, including hanging paper towel holders on the inside doors and getting silicone mats to prevent spills.

Also, gloves. Every time. Every time I open that closet the first thing I do is put on gloves, even to touch the tools. I have no idea what still has resin on it, so I trust nothing in there.
