Flexion Extruder Cr10 for Microswiss/MK8 and Vulcano

cults3d

I need all STL files for 42 mm or 32 mm stepper motors that are compatible with Vulcano, Micro Swiss, or stock hotends. I specifically want to improve my flexion on my CR10 printer because I primarily print TPU and extremely flexible materials. Other options exist for flexion upgrades, but I'm looking for a design where the stepper motor sits atop the axis rather than at the front, preventing weight from accumulating in the front and causing it to vibrate. Additionally, I prefer an extruder with the flexion part facing forward and being easy to handle. For 42 mm stepper motors, there's the "flexion_fanholder.stl" file which includes a holder for the fan and a wall to prevent hotend fans from blowing downwards. The "Flexion_Extruder__stepper_32mm.stl" file is designed without a fan wall and is slightly flatter for use with smaller 32 mm stepper motors. There's also the "flexion_vulcano.stl" file, which is intended for higher Vulcano heatblocks. I use this option when printing ABS because my high-speed prints (100-180 mm/s) using Octoprint Klipper software cause the normal hotend to jump due to its short heating path. The longer distance required for the filament to heat up and melt with the Vulcano hotend eliminates this issue. To clarify, I'm not suggesting replacing the stock hotend or Micro Swiss; instead, I recommend mounting the Vulcano heatblock on either of these options. These designs work perfectly for printing ABS, nylon, PETG, PLA, and TPU.
