CR Touch Sensor pin spacer

Spacer to fix “key: 2194” error while bed leveling with CR Touch

For a while I’ve been printing with my Ender3 V3 KE, and I’ve had the “key: 2194” error a few times. Reading through forums, the usual recommendations are to lubricate the sensor or sometimes replace it… until I came across a comment suggesting adding a spacer on the metal pin. This actually makes sense, since it prevents the pin from rising too much and getting stuck in its housing, which causes the error.

I’ve included the dimensions of the model. These dimensions may vary depending on your printer when printing (tolerances and actual real-world measurements). The part is designed so the spacer can be easily removed from the support.

There are two height options for the piece (0.4 and 0.6 mm). Choose the one that best fits your case.
