Quick Release nut spring loaded UPDATED

Update:
I have added new version which slides onto itself, no glue or screws required, much easier to align(because there is no align needed at all) and to assemble, can be opened if needed . There are holes ready to be used with piece of filament as a pin lock if necesary.
Tested pieces printed are:
height: 0.2mm
width:0.48mm
4bottom layers
4top layers
4 perimeters
infill 35%
material used: eSun PLA+


Remix for m12 version of this quick release nut as the original have very poor mounting for spring, i also added second version with thread on the casing to make it more steady, button is redesigned to secure spring better and is a bit longer over all to increase the grip and to make it easier to assembly.
Fast nut m12 + fast nut m12 button is with smooth casing
Fast nut m12 A + B + fast nut m12 button A is with threaded casing (on part A and button there is small square, they both have to face side B to make thread properly aligned.

Printed with 4perimeters and 30% in
