FreeABL nozzle prober for V6 hotend

Free ABL that uses the nozzle for probing the print bed.

This is more ment as a proff of concept, and it worked very well for me, since it does not require buying any specific new parts.

(3mf files can be opened in cura, for those who dont know the file format)

Works best on hard surfaces like glass.

this version is curently mounted on my sunlu-s8, i havent tested the mount plate on any other printer, but it should work on a CR10 and Ender 3.

the bearings needed are

it is designed for the E3D V6 hotend.

2x Ø16mm (outer diameter), Ø5mm (inder diameter), 5mm thick (can be found in nema 17 stepper motors, mine is from a dead nema 17 stepper motor)

the arm can be monted with a long m5 bolt.

for the switch, it uses a standart endstop switch with Ø3 holes, spaced out 9,5mm

the spring i used is a Ø7x15mm spring ( dont use strong springs, or you will damage your nozzle/hotend/carriage ) and a stiff mounted print bed, for best results

(please exuce my spelling erros, im dyslexic and i will go over everything once my autocorrect on my pc works again -__-" ... )
