FolgerTech Kossel hotbed adjustable mount. Easy to calibrate.

I'm tired of calibrating my Folger Tech 2020 Kossel using z-probe. Tried both - Marlin and Repetier. They calibrate, but I didn't like the final results. The stock Z-probe is too far from the tip (X-Y offset) and even slight effector tilt return very inaccurate values.

So, I decided to make my own adjustable hotbed mount using spare screws from printer kit (3 M3x25, 3 M3x15, 3 Nylock M3 nuts, 3 washers and 3 M3 t-nuts for 2020 extruded profile), simple sketchup-made mount (printed using PETG)
