Inductive proximity z-probe adapter. Works with glass cover.
thingiverse
This adapter works best when attached to detachable probes or used as a temporary calibration attachment. Don't attempt to permanently add it to probes that are only 2-3 mm higher than the nozzle. My aluminum Kossel bed isn't perfectly flat, so I covered it with 3mm glass for a better printing experience. However, my inductive probe stopped working afterwards. I came up with this adapter to solve the problem. You'll need a #14 0.08" (2mm) nail and a very light spring - like the ones found in this kit from Home Depot: Everbilt Spring Assortment Kit-84-Pack (item number 15642). Actually, it still works without the spring because of the weight of the nail/tip. Alternatively, you can replace the spring with a thin U-shaped piece of plastic (from a PET bottle or similar). This modification doesn't affect sensitivity and precision. Just don't forget to adjust your z-probe height in the firmware afterwards. You can find a video that explains how it works on YouTube: 83hY3M8QLtg. There's also an animated probe video: C8dT_2mZWXk. This adapter was printed with PLA at 180C, using a 0.4mm nozzle, 0.2mm height, and manually set width of 0.5mm. The print settings included 30 mm/s speed with slicer cooling enabled for optimal cooling. Print Settings: Rafts: Supports:
