Sk-Go Kinematic leveling

thingiverse

There's a trick to installing the 3-point ball and rail Kinematic leveling system for Sk-Go. First, thread the spring screw into the corner plastic pieces from the back first, forming threads as you go, then insert them in the front. It's best to glue everything together - I used JB weld Steel, which is incredibly hard and heat-resistant, having successfully glued falling bed magnets on my Prusa with it a couple years ago after printing ABS nonstop. Glue the M3 nut into printed parts first, followed by the Dowel pins for a clean fit. Next, glue lock-nuts into printed lock-nut parts to prevent play when turning the knob. Use lock-nut parts at both ends of the extrusion and attach them with some M3s and T-nuts. Here's the bill of materials from McMaster: * 3x Springs: 9065K413 * 3x m3 nuts * 6x M3 lock nuts: 93625A100 * 6x dowel pin 3mmx16: 91585A379 * 3x M3 hex head screw: 91287A028 * 3x M3x 8 flat head screw: 92125A128 * 3x M3x12 screws to attach the spring on printed parts * 3 sets of M3x10 screws with T-nuts to attach the other side of the spring For the balls, search for "Threaded 6 mm Stainless Steel Balls M3 HALF Thread" on eBay - they're usually used for building puppets.
