A quick assortment of limit switch mounts or clamps. Optimized to some extent for Prusa i3 with wooden box frame or the flat plate style frame.
X Axis
The four with “8mmRod” in the name clip onto the two smooth 8 mm rods for the X axis.
The improved one works on the tighter spaces of the flat sheet style Prusa i3.
The offset style is good for working around a bulky extruder.
Z Axis
The three(now four) parts with “adj” in the name are for an adjustable Z endstop. Loosly derived and somewhat sturdier version of http://www.thingiverse.com/thing:149882.
The short version allows use of a hot end that is barely longer than the bottome of the X carriage. This maximizes build volume. That is good!
The part that mounts on the left hand Z stepper motor is designed to fit a Micro Switch V3 101 or similiar(the last batch I got were labled V7-7B19E9). They seem to be accurate enough to work as precise Z axis limit switches which is better than some other switches I’ve tried. Still looking for something less massive that is just as accurate.
Y Axis
There is also a modified version of rrhb’s http://www.thingiverse.com/thing:15683 which works well as a Y axis endstop in some cases.
I’ve also modified http://www.thingiverse.com/thing:153851 to fit a common size of limit switch. That’s the one I use the most now.
Another version places the limit switch vertically, and has four holes to help fit assorted switches.
