Static build up?
I run my Mini in a Lack enclosure. I’ve noticed small static electrical buildup. Not enough to generate a spark but enough that small bits of plastic (say from printer calibrations) will jump and stick to the acrylic walls. And if I print very thin parts, I notice that they will static cling to the build surface even if I’ve broken them free.
Any ideas on what’s causing this and how to mitigate it?

I don't know what is causing it, or how to mitigate it, but I would try earthing your enclosure and see if that helps at all.

I had the same problem several times with my MK3. Maybe it is because of you (statically charged). The best thing to do is to discharge yourself on a grounded object.

Not sure how to do that. Several paint-coated paper-wood-pulp surfaces separated by PETG as well as Acrylic windows.

Understood. Except this happens without me. Scraps apply themselves to the acrylic.
It could be additive by the air from my AC system blown over the enclosure. Not sure.

What is the humidity in the room, as it say it could be the air conditioning blowing very dry air over the enclosure.
Try an anti-static cleaning spray on the in and outsides of the Acrylic windows.

Dry air favors the formation of electrostatic charges. A room air humidifier can help if the correct humidity level is reached, e.g. something like this:

I think to start with, to see if this helps, a metal clip on the acrylic, or even tape one to it, with a wire to a grounding point. If it works you can think about a permanent solution which would probably involve drilling holes and a nut and bolt.

I noticed some static cling on a few thin ABS scraps today. This is the first time since last winter that I've noticed it. The humidity gauge in the home office shows 33 percent, which is about what we usually have inside during the summer.
RE: Static build up?
Thanks, all, for the suggestions. My house (downstairs) runs about 55% humidity most of the time according to my thermostat. It’s not excessively dry.
I’ll see if there’s a spray that might help before I try anything more invasive.
