Custom tube cap with guard

This is a customizer for a press-fit cap for tubes with a guard to avoid loss. Don't print the guard if you aren't using flexible filament. The guard is to attach the whole thing to the tube or something and avoid losing the cap.

Recommended print in flexible materials. I am using it for lab test tubes, for caps for my vaping atomizers, for oil bottles which its original cap broke, etc. Cheap, prints quick/easy and is reusable/customizable.

Enjoy!
