Ever wanted to go outside and have a joint ready so you carried it in a nice box? Well this one is even more nice then the other designs you might find as it is cone shaped on the inside but perfectly parallel on the outside.
The length of your joint may be up to 10cm - typical longpapes are 10.7cm long, but you will not use them completly anyway so this ensures a perfect fit once you twisted them at the top.
To get a stuck in joint out just firmly shake it and cover the tip with a finger.
Print without any supports and vertically but maybe add a brim to the bottom side so that it sticks well to the print bed.
The tolerance for the thread should be fine to just work smoothly - at least was on my Prusa MK3 with .2mm layer height.
