This could be it, OP should check what the actual temperature says on the screen during printing.

Aside from drying, here are some thoughts:

Double-check the print temperature, PETG should be about 240-ish. Also the spiral vase mode may be the issue if your model isn’t designed for it. Also check your z offset, the first layer should be almost a flawless sheet… if not, stop the print and try again while live adjusting the z until it’s correct. Typically PETG doesn’t like to be squished down as much as PLA.

I printed the panels using the full width of my large 300x300mm print bed. I have three of them mounted to the wall. There are several sizes available though, you can always merge more smaller ones.

It’s actually just a shorter version of the tall basket model that was available. I originally meant for it to hold my alcohol bottle, but it was too small… then I discovered it fits the canned air perfectly.

Don’t question my methods lol

Neat, good job. You might want to include what screw size it fits, and the word “anchor” somewhere in the description/title for searching (these are typically called drywall anchors in the US).

This is their thicker (and more expensive) enclosure, I haven’t noticed any issues. The back end of the dryer is right over the corner joint to hopefully add strength.

It’s significantly faster, the higher motor resolution reduces vertical fine artifacts, and the nextruder reduces texture that could otherwise be caused by bad drive gears.

Tukkari support told me directly to do this. It barely gets warm under the dryer, so there’s no real risk of it damaging the plexiglass.

Case is great, I like not having to mess with moving the power supply or display. It’s designed around having the PSU inside the enclosure, with dedicated air ducting to the PSU vents. It is a little noisy with the printer vibrating the melamine base like a drum on top of the enclosure’s plastic feet… I’ll suspend it on foam and/or a paver someday. It also removed the hot plastic smell from the room entirely (I’m sensitive to it).
