TRV pin spacer

This is a spacer for a Thermostatic Radiator Valve, also known as TRV.I use Hive Smart TRV heads, which don't have plenty of range of motion to control the TRV pin. When they don't fit exactly right, they can never fully close the valve.This tiny little spacer solves for this. Its diameter is measured to fit a standard TRV pin snuggly and adds 2 millimetres of height to the pin, enough to be able to be controlled by the TRV head.If it doesn't, scaling it up or down should be trivial to fit your needs. Due to the high temperature environment this needs to operate in, PLA would not work. I am not sure about PETG.I print mine with ASA. ABS or similar high temperature tolerant filament should also work.
