This Support for the Z Axis End Switch has been created in order to avoid unprecise and inadvertent changes of the position of the Z Axis End Switch.
In addition it anticipates any variation in thickness (in + or -) of the heatbed, especially in case of replacement of the original one by a glass one.
This Support can be moved up and down and firmly locked into the suitable position without the need for any modification of the printer except for the M3 bolt which is to be at least of 20mm long in replacement of the original one which is 16mm only.
It has been specifically developped for the Sunhokey PRUSA I3, even if it can fit without adapatation (or minor) to other printers which has the same kind of frame.
The file originally made with SKETCHUP is also attached for eventual adaptations.
