Sovol sv06 anti backlash

Here is a suitable improvised anti backlash nut for the sovol sv06.

There is not much clearance at the top of the sovol between the z-axis stops and the bridge (24mm).

Finished antibacklash nuts are too long. (I didn't find any suitable)

You can use the adapter, 

https://www.printables.com/de/model/686558-sovol-sv06-spindle-nut-adapter

to install two standard spindle nut. 

(one of the nut you have to drill two bigger holes. see link.)

You first have to see which holes match when you screw the nuts on top of each other. There shouldn't be too big of a gap between them otherwise it could become too long. 

Under no circumstances should they be screwed tightly together, otherwise the spring will not serve its purpose. If no hole fits properly, the top nut can be shortened slightly until it fits.

the two guide screws of the upper spindle nut must not protrude below the lower spindle nut flange.

what you need:

to fix the bottom nuts

4 M3 x 16 screws

4 M3 washers

For the top nuts in my case

4 M3 x 18mm (M3 x 20mm shortened) 

4 M3 nut

2 compression spring

0.8x12x40mm

You have to screw them in together then tighten the bottom screws through the holes

Ideally, the compression spring should rest between the M3 nuts and the lower washers.
