P.I.N.D.A. PROTECTOR for 12mm Inductive proximity sensor LJ12A3-4-Z + VIDEO

Read the print notes please! Now with correct M12x1mm thread instead of M12x1.75mm. I noticed that Prusa has an additional item on their website called a P.I.N.D.A. protector, a snag protector for an inductive proximity sensor designed to prevent warping or peaking parts from hitting the probe. Since the Prusa MK2 uses a smaller diameter probe, this doesn't fit with the widely used 12mm version LJ12A3-4-Z/BX or BY. So I created one using Autodesk's Fusion 360, just like many of my other designs. I hope you'll enjoy it as well! This sensor only detects metal print surfaces. When using a build mat such as Buildtak or Lokbuild, you might want to upgrade to the LJ18A3-8-Z/BX dat can detect up-to 8mm away, which is much less when using aluminum beds. This way your 12mm version will not hit your prints and upset the positioning of the head/nozzle when a piece of the print sticks out slightly. Because the bottom of the sensor will be at the same height as the tip of the nozzle. You'll appreciate this later.

Printer: Prusa Z3D Rework (Awesome Custom) Rafts: Doesn't Matter Supports: No Resolution: 0.2 Infill: 20-30 Notes: If your print shrinks after cooling down like ABS does, the P.I.N.D.A. protector might not screw on properly or at all. Do not force it on. Just print a new one at 1-2% larger scale. I used 102% scale with ABS and it was tight. It should fit snugly. If too loose, it will unwind itself by vibrations and mess up your bed leveling.
