Hello everyone! This is my tool for remove the tiny valve inside the tire valve. Normally is an iron tool, but there is in plastic too. I used PETG and works perfectly.
Didn't work for me. Printed perfectly but the ends both snapped right off the first time I tried to use it to loosen a valve core.
Printed in PETG-CF, 3 walls, 100% infill, changed layer height to 0.16mm
I'm so Sorry for what happend.
This valve don' t Need much torque to be closed because they have a rubber o-ring to keep the pressure. Maybe Someone before you tight It like a normal Bolt.
Anyway to recover your valve you can try warming up a metal PIN with a lighter and then put It inside with a plier to touch the 3d printed parts and make lever.
Thank you for the feedback
