Sex machine connector plug (AKA 'quick air') and some attachments for it

DISCLAIMER: THIS WAS MADE BY AN AMATEUR WHO CAN NOT GUARANTEE THESE MODELS WILL WORK SAFELY OR AS INTENDED. FOR YOUR OWN SAFETY YOU SHOULD TEST YOUR PRINTS THOROUGHLY AND BE VERY CAREFUL USING THESE DESIGNS.

Hismith calls this connector ‘quick air’.

The automotive and industrial sector call this a ‘Pneumatic Quick Coupling with Japanese Industrial Profile’. (Europe and the US use other standards)

But most importantly this is the connector that you need to print your own attachments for sex machines from Hismith or from Aliexpress.

1. Make sure this is the correct connector for your machine
2. Add this connector to whatever model you want
3. Print it in PETG (to give the connector strength)
4. Attach your model to the machine
5. Enjoy

I also included a fleshlight compatible screw bottom which uses the connector. It is based on this model.

UPDATE: I included a model that I use to attach dildos using rope.

For the love of god print this in PETG with a high infill. PLA WILL NOT BE STRONG ENOUGH.

(note, as an alternative you can buy these connectors cheap from aliexpress by searching ‘quick air coupling’)
