My 3D workshop? A somewhat large custom fitted closet. The printer sits on a extending/sliding base and there are shelves with the filament boxes (I use resealable containers).
The printer is fully enclosed (adapted U1 with a chamber heater, a chamber air filter), but the cabinet itself can also be ventilated with a exhaust going through a custom made filter array (HEPA and activated charcoal. A mate of mine is builds those for a living/has a PhD in it, so it is somewhat sophisticated) or unfiltered. Additionally I installed a light and various temperature probes in it.
These days a small display should arrive that I want to fit outside it, so I can control the printer, vents,etc. from there, via Home Assistant. In the long term I will also slowly replace the cheap hygrometers I now have with ZigBee ones so I can list all humidities in the display.
Additionally I have a Chitu E1 and a Gratkit for drying. While the Gratkit fits, I haven't found a good space for the Chitu yet.
Next to the closet is a height adaptable desk I use for electronics and things like that so I have my post-processing tools there as well.
