A tool to remove or tighten the service valves (Schrader valve) of cooling-/ heatpump systems. My standard tool is sometimes too big to use it properly.

But it should work on the valves of tires too.

I´ve printed it in PC, because in my job it will get in contact with hot, oily objects.

0,4 nozzel, 3 perimeter, 6 bottom/toplayers, 30% grid infill.

I´ve used it several times. Works well until now.
