Adjustable BL-Touch sensor mount for Ender 3 and CR10 (with STEP file)

This is an adjustable (up and down) mount for BL-touch, and BL-touch type sensors. It is designed for the Ender3 (and therefore also the CR-10 and other Creality printers that use the same hot end design).

This thing is a mash up of the rails used in Chito's "CR-10 Heavy Duty customisable modular e3D V6 mount Volcano 5015 ABL", and the mount used in Lucid's "CR-10 BLtouch mount", and is designed to be adjustable.

<h1>tl;dr:</h1>

These are the recommended files to use/print:

Base Mount:
<strong>adj-bltouch-mount-3D-mount-EC-mod.stl</strong>

Why use this version? Because it has pockets for the fan cover, print with supports.

Wing:
<strong>adj-bltouch-mount-4A-wing.stl</strong>
-or
<strong>adj-bltouch-mount-5C-Short-Wing-M25.stl</strong>

Why use one of these? Because these print faster and have more adjustment range. The difference between these is that the "5C-Short-Wing-M25" version allows the M2.5 nuts (which mount the probe) to remain captive in a pocket. The "4A-wing" does not have pockets for the nuts used to mount the probe. No Supports needed.

Hardware:
The mount itself will need a 10mm M3 screw and a M3 nut. Note that this is in addition to the mounting hardware for mounting the touch probe to the mount.
Optional is some nail polish to help hold the M3 adjusting screw once it is set where you want it - <strong>thanks ixian for the idea</strong>.

All files can be printed at 0.2mm layer height.
