thingiverse

I was thrilled to reuse the Z-Stop I had readily available after installing the BL-Touch, but I wasn't too keen on having the sensor just dangling off the filament. I revamped the parent design from @The_Goss to securely attach it to the Z-Stepper mount. All the instructions and examples from his model still apply; now you simply slide this into place over the Z-axis roller spindle. v2 - Complete Mount v1.3 - Sensor tray only for remixing into other mounts/parts ***Updated 2/7/19*** 1. I added v2 STL and F3D files with integrated Z-Stepper mount. ***Updated 2/6/19*** 1. I fixed screw hole alignment. 2. I thickened the backplate to better align switch/connection. 3. I filleted all the things! 4. I centered and deepened connector notch. ***Updated 2/6/19*** 1. I loosened tolerance on PTFE cutouts. 2. I added a cutout for wiring connector on bottom face. 3. I increased front wall thickness on tube enclosure. 4. I enlarged cutout for sensor arm
