Kossel Z-probe mount with optical switch

thingiverse

I upgraded the design on May 3, 2015 to increase clearance between the magnet and wrench. I had to tone down the magnetic strength. To accomplish this, I narrowed the top section. The Kossel mini will use this custom Z-Probe. It was built around a strong rare-earth magnet retrieved from an old hard drive. I altered the Allen wrench as well by shortening its length to ensure proper assembly. This optical switch for Z-probe is purchased through eBay here: https://www.ebay.com/itm/390986451783 To remove cone-shaped guides and enlarge holes for bolts, simply use a small pair of pliers or wire cutters.
