Enclosure is mostly to keep cat hair off my printer (my cat sheds like crazy) and to filter some of the microplastic dust and fumes. It does reduce warping by keeping the volume warmer than room temperature, I print a lot of PETG so this helps.

I think it’s either US or German built, no idea though.

Yeah, I’ll owe about 5k fed tax and my W4 is set up so I usually pay/owe nothing come tax time… so I’d currently get about a 5k refund. I’m looking at ways to increase my federal taxes before EOY to squeeze more out of it.

Dang, I need to try that. Good idea.

It might just be the specific spool/brand of PETG you used. Try buying some from a major well-known manufacturer, like Overture, Polymaker, etc. I’ve had cheaper brands shrink, warp, have adhesion issues, and all sorts of other quirks.
