I wanted to produce a water-tight vase to use for cut flowers. My print setting should work just fine for PLA or PETG, just remember to change the filament when you load the 3mf. I can only attest to it being water-tight with ASA for now. Scaling will work, just be careful to check the "uniform scaling" box if you do. I will upload settings for other filaments as I test them. Thank you for checking out my vase and please share your prints I'd love to see them! Thanks again and Happy Printing!
