CR-10 Bed Level Dial system

thingiverse

This is a system designed to level the CR-10 3D printer bed using four dials at the front. Four sets of gears turn beneath the bed, meshing with screws that adjust the bed height during operation. One dial spin increases the bed height by .25 millimeters without placing hands under the bed. The system works with a square rail transmitting rotations from a front dial to a gear that slides along the shaft and is held next to the leveling gear. The leveling gear fits around the hand screw adjusting the bed height. A non-circular rail, available at Walmart or eBay, is the only component not printed: a 3/16" x 3' metal square bar. Specifications for the Shaft Gear include: Teeth: 7 Helix Angle: 60 degrees Module: 1mm The Level Gear specifications are: Teeth: 20 Helix Angle: 30 degrees Module: 1mm Adjustments may be necessary for HickTop vs. Creality versions, but this design can be modified to fit other platforms with similar bed leveling mechanisms. Assembled parts are available in a combined Fusion 360 model (a360.co/2kIADDH). Optional modifications include mirroring two slide gears and associated thumb screw gears to allow all four front dials to spin in the same direction, moving the bed up or down. This setup also enables attaching a camera.
