8-13mm Hose Adapter

Story: I needed to connect the hose (https://amzn.to/4gGKDXH) of my mini pump (https://amzn.to/4k0SBh2) to a regular 13mm hose (https://amzn.to/4jYIidh) to be able to attach a Gardena quick connector (https://amzn.to/3QiqNHp). After the first version, I have added some chamfers so you can print without any support. If you have any trouble fitting the hose onto the adapter just dip the end of the hose into hot water for one or two minutes.

I have used PLA but you can also use PETG and ASA filaments:
