I designed this bracket to snap on to an E3D-V6 heater block and to hold a tiny microswitch as a Z-Probe for calibration. (switch source http://www.goldmine-elec-products.com/prodinfo.asp?number=G16909 )

Wire up a disconnectable harness, and just snap the bracket on and off when you want to run a calibration cycle.

Note that the STL file has printed support built into the model. The STL file contains 3 separate pieces.

Don't use the bracket while the hot-end is hot.
