Inside Diameter Calipers

thingiverse

An effective tool for gauging internal dimensions; a clever trick involves swinging the legs to convert it into an outside diameter caliper! Tip: Be sure to reverse the threads on the knob, as this design feature enables its use in oxygen systems without requiring additional supports during printing. The reversed treads also ensure that the knob securely screws on and holds everything together—no vitamins needed for proper functioning!
