The pin swerves togehter and holds the plastic wrap in the package. espacially after you hade to take out the roll when the wrap did got stuck.
The full lenght when screwed togehter is 340mm. The female part have a lenght of 178mm. The male part have a length of 200mm.
I recomend to strangethen the print with additonal thicknes to the outer walls. This can be done in Prucaslicer when you have added the stl. In Prusaslicer goto “print settings” → “vertical shells” → change “Perimiters” to 4 and this gives a wall thinckness of 1,67 mm when using a 0.4mm nozzle.
It can also be good to change infill to 50%, also for strength.
