Knife Sharpening Tool V3

I really liked CNCKitchen's sharpener design, but I wanted some extra refinements, making the construction a bit simpler, using not so many different types of screws. So here's my remix. Changes from V2.1: redesigned handle for quick switching of stones. moved legs forward 2 cm for extra stability added hole on bottom for adding a 40mm suction cup tighter tolerances for 10mm tube holes. tighter tolerance for guide-slot. changed screw-mount for vertical tube to press-fit. added a cap for vertical tube. capped holes on feet. added user Badpassword's guide (great print-in-place design) optional 10mm handle & guide so you only need 1 size tube. Created smaller angle guides, you need these to be able to set the angle on the knife itself, to compensate for knife angle. Hardware needed: 2x 10mm diameter x 180mm aluminum rod/tube for the body 6mm (or 10mm) diameter x 280mm aluminum rod/tube for the handle 1x M5x30mm hex head bolt + Washer + Thumb Nut for knife guide. 1x M5x 30mm hex head bolt + nut for handle glue to fix rods in place. 10x 10x2mm disc magnets (optional) optional 40 mm suction cup for extra stability Sharpening Tips: get a set of stones for example 1000,3000 and 6000 grit. Start from lowest grit. Soak stones before sharpening. sharpen one side of blade until you can feel a burr, then change side, then move to higher grit. only apply pressure on the push stroke. don't apply pressure on the pull. cover about an inch every stroke, work your way along the blade. keep the blade edge parallel to the sharpener edge.
