Your earlier models look kinda cloudy, which means they still have moisture in them. You can pop em in an oven on the lowest setting (104 F to 122 F) and keep an eye on them for a few hours. Just set them on a foil pan you don't mind losing, and keep setting your timer for every ten to fifteen minutes until your piece isn't foggy or cloudy anymore. Also, don't breathe the fumes when you open the oven, and use a fan to just clear them out for a few minutes when you're done so the moisture doesn't stay in there and get on food you cook later.
I know for a fact that a layer of epoxy on the inside can make it a lot stronger. You just use an applicator stick and spin it around to apply the layer inside a long container. The thicker the layer is, the stronger it'll be.
One last thing. Have you tried orienting the container designs on their side so that they're printed with the opening facing the side instead of straight up? Different orientations create different internal structures that are stronger against stress from a certain direction of pressure.

Been meaning to use it again. Just busy...

It can be acetone smoothed... Not sure about alcohol.

How much drying is a lot?. Like 24 hours on the dryer box? I've dried PETG for over 15 hours to get really pristine prints.

I try to print PMMA... and I have got from nontransparent print to something mostly transparent with random holes in the wall... And also, the bottom 17mm tends to be always white nontransparent. I wonder why is that happening... I thought whether the temperature of the bed is not the culprit... but even if I lowered temperature from 100°C down to 80 °C, the result is the same.
Over that 17mm the print is becoming clearer... it looks like 30mm/s print is much better than 20mm/s... It was also strange that the print improved considerably when I lowered nozzle temperature from 250°C down to 230°C.
Still those random errors in the vase mode 3D print... Could it be that the 1mm diameter nozzle generates it? the nozzle has 3 convergent holes as inlet for filament to make larger surface for heat transfer into filament... Maybe some air comes into the plastic that way?

I've heard it smells awful. I've always wanted to try it out but too scared.
