Description
Here are some improvements I made to the Knife Sharpener Upgrades from @firstgizmo. ( https://www.printables.com/model/703710-knife-sharpener/remixes ) It includes: - A magnetic holder for small knives. - A magnetic holder for large knives. - A reinforcement to prevent the screw that holds the sharpening stone from bending. (In the original design, this screw would bend over time, even though the stone wasn't tightened much against the knife. Now it won't bend anymore.) For me, it's now perfect in every way and has left my knives perfectly sharp. Everything has been tested at 15º and 20º angles. I imagine it works with other angles as well, but I haven't tested them. I used 5mm x 2mm round magnets and super glue to attach them so they wouldn't come loose. I printed everything with Bambu Lab A1 and A1 mini printers in standard settings using regular PLA filament. Everything was done with 60mm wide stones and grits of 240 / 800 / 2000 / 5000, making 50 passes on each side with a knife at all grits. I hope you find it interesting and useful. Thank you very much.
