Grungy's Clip-On Dual Gear Direct Drive (Ender 5)

thingiverse

A lightweight and unobtrusive drive mount for any stepper motor using the Winsinn Dual Gear Extruder is easily achieved with this design. The mount has been confirmed to be non-obstructive with various duct designs including Hero Me, Petsfang, and Hydra. I personally use this mount with a 34mm Nema 17 motor and have found it to be stable enough for daily use. However, any Nema 17 motor between 23mm to 48mm will fit. A bolt-on version of the mount is also included for added security. The design has been tested with clip-on and bolt-on versions and both have proven to be extremely stable. ### Print Instructions The print can be done using supports and brim in the STL's original orientation. It is recommended to use Cura's Tree supports in experimental settings to save plastic. Add "Support Blockers" to the left and right ventilation holes, as well as the front Nema screw mounts. Be mindful not to put the support blocker on the top most overhang or the central giant hole. It is not recommended to print this design in PLA due to warping caused by heat generated from the stepper motor. Instead, use PETG, ABS, or PC which have high heat resistance and provide a slight amount of flex to prevent the clips from breaking on insertion. Since these designs are press fit, they require high dimensional accuracy. Prior to printing, it is highly recommended to calibrate your printer in this order: 1. Extruder e-steps 2. X/Y/Z Axis e-steps 3. Cura's horizontal expansion value Note: "Flow" calibration is not needed and over extrusion would result in a slightly stronger part.
