Prusa i3 Z End-Stop mount [Folger Tech]

thingiverse

Here's a better mount designed specifically for my Folger Tech Prusa i3. The stock mounting bracket was unreliable and prone to breakage. Check out the attached pictures and make sure to maximize them since they're truncated on this webpage. I recently realized that I had missed including any side shots - those have now been added. There's also a side-view video at http://youtu.be/dZHDUUFaER8. This mount attaches directly to the Z-axis stepper through the acrylic base using some spare screws left over from the assembly kit. The original short screws holding down the motor were replaced with longer ones to ensure a secure hold. I made some adjustments to prevent the guides from flopping around, and I'm satisfied with this setup for now - it's working great. The square guides keep the adjustable piece firmly in place within the base, while an upside-down screw enables precise adjustment of the end-stop height. Optional slots have been designed into the mount to accommodate nuts, although I discovered that screws of similar diameter fitted perfectly without requiring nuts. The hole cutout in the adjustable mount is designed to fit solder joints on the backside of the end-stop. When handling the guide component, be gentle as it can break easily; superglue proves helpful for repairs. For those interested in tinkering, I've included OpenSCAD files.
