This is an experimental antibacklash nut to be used for 3D printers and small CNC machines.
This nut uses two metric M8 nuts, one standard DIN 934 and one thin DIN 936 nuts.
Adjustability is achieved with M5 screw that can be screwed on its place without tapping the threads. It should work ok. If not, use M5 tap to make the threads. You can of course use also for example heat inserts, nuts (you have to remix for these)
Not printed this one yet - test print is up the next... :)
