This print is a lid for an Ikea jar. I printed it in PLA from PolyTerra and PETG from Prusament.
[PETG]: In Prusaslicer I resized the part to 100,5% for a good snug, but not too tight fit. For the colour “Ocean Blue” it was perfect and for the colour “Lipstick Red” it is a bit looser.
[PLA]: No resize needed for a tight fit.
