This is a minor modification of PrecisionPiezo Orion Mount for Creality printers: CR-10, CR-10 Mini, Ender3 by cassianoleal. I've simply added two drill guide holes to mount the Zesty Nimble Extruder. I then used a soldering iron to install some brass M3 hot-inserts into the new holes to secure the nimble.
There are still two versions: one with and one without triangular wedge supports.
Note, I did have to manually drill out all the bolt holes and the mounting holes. Also, because I'd printed with with damp PETg and no part cooling the domed recess at the back collapsed a little and also needed drilling out.
The photos show that I'm actually using an LJC18A3-B-Z/AX capacitive proximity sensor rather than the Precision Piezo Orion. This is because I'd accidentally damaged the piezo and have had to go back to the heavy capacitance sensor. The capacitance sensor is actually working very well but the piezo makes the hot-end lighter.
