Print Orientation
Flip models upside down so they are printed face down on the plate ("F" in PrusaSlicer) – they'll look great and won't require any supports
Tightness Adjustment
All printers and filaments are different, you might need to adjust scale of the caps to achieve perfect fit.
I suggest you print one piece first and try it. If it's too tight – upscale a tiny bit, if too lose – downscale. After finding the perfect fit – print as many as you need. The difference between perfect and acceptable fit can be 0.10-0.20mm, which is only 1-2% up or down.
