Nema 17 1:4 Planetary Geared Extruder

thingiverse

Here is nema17 version, a motor upgrade compatible with any nema housing sporting longer than 25mm shaft lengths. Its functionality leverages the motor shaft as an extruder shaft. Due to its different operating speed, please grease the shaft and MK8 gear generously for added protection against wear. Kindly refer to print setting notes listed below: Rafts: Absolutely none. Supports: Absolutely required. Resolution: We are talking 0.15 here. Infill Percentage: Sitting comfortably at a solid 50%. Notes: Specifically designed to support Body2, however do keep in mind these crucial rotation directions for successful printing: - Rotate Body1 by exactly 180 degrees on the X-axis. - Idler requires a full 90 degree flip. Gear-wise, we have chosen an ingenious workaround of applying -0.12 XY compensation within Slic3r software on our trusty printer to perfect the design. Post-print processing calls for precision and finesse: Drill precisely at both Gear1 with 3mm drill bits. Conversely, carefully manually drill the Orbit portion using robust 5mm drill bits, ensuring you eschew drilling those precise 3mm holes – it just won't do.
