I have no access to medical equipment, so I’ve designed this blind, if you have information or suggestions for improvement please let me know and I will update / re-release.

This is unprinted as yet.

Please use medical or food grade for printing, but whatever you have to hand may be needed.

I’ve used similar methods for printing female ports at the base, but this is the first Male at the base.

This is 100% open source – use it if its good for you, redesign, remix, change sizes, modify or ask if I can modify for you, I’ll help if I can.

UNTESTED.

UK Gov has fecked up and I’m hoping we can stop their negligence becoming a catastrophe. Here’s their guidance.
