The Placentia Library in Placentia, CA, has one. They bought the pro and built their makerspace in the middle of the library. The main issue for them was ventilation. They bought the air filter, but it’s not really supposed to be used with MDF, and even with the cheap plywood they were cutting, they had an issue with smoke and fumes in the little room.
When they renovated the library, they didn’t think about adding a vent to the room, so they have to open the makerspace doors, and then the smell goes into the library. The space has been closed since the pandemic, but they were debating about cutting a hole into the ceiling to route the fumes out another way. Not sure if they ever did that.
That was the biggest complaint they discussed with me. They also started implenting an appointment system. So now they have a 20 minute policy and you need to bring your own materials. I had a friend go and they wouldn’t let her cut MDF because of the fumes, so she sent the project to me and asked me to cut it for her.
