Technical Tips for 3D Printing

Material: PETG, because it's a neutral material, or ASA if exposed to intense sunlight.
My recommendation: if you want to take plastic neutrality a step further, which is almost impossible with manufactured products, opt for PETG certified for food contact.
PLA: not at all suitable for this purpose
Orientation: Easy to print flat in 0.2 mm
