Din-Rail ('Hutschiene') mount for components

Sizes (screw_along and screw_across as well as other parameters) can be easily configured in openscad file. Makefile generates the STL.

Hardware

A spring and slider printed in place provides the clip-on action.

Since the slider is printed in place, make sure to not too elephant-foot your first layer too much; might need to be opened up a bit after printing for the slider to be free.

Can be printed with open or isolated bottom:

Open	Isolated

The spring and shape of the hook make it snap into place with a satisfying click.

Printed in PLA, ABS and PETG and in all cases the spring-force is roughly right (but can be configured with spring_height and spring_thick).

Examples

Relay mount	Isolated Relay back	Solenoid
