Knife sharpener

Hi, My goal is to have a 1 buildplate print and easy to use knife sharpener that uses a sharpening stone.For the ease of use I used the bearings from here: https://makerworld.com/models/473167They make it easy to slide back and forth.The bearings snap on the angled block. I bought a sharpening stone from amazon.Max with for the stone in this print is 65 mm. Make sure too put some antislip on the bottom of the base or a wet towel to keep everything the knife sharpener in place. Please leave comments for any improvements, adjustments I could make. Thanks and Have Fun
