Z axis support for Pursa i3 clone

thingiverse

This is a custom Z axis support designed for my modified Prusa i3 clone (Geetech), specifically engineered to accommodate an inverted Z axis configuration, where Z motors are positioned on top. Thus far, I have not encountered any significant issues with this setup. However, numerous discussions across various forums have raised concerns about the stability of my current arrangement. To gain a deeper understanding of the printer's performance without this support, please visit my YouTube channel at https://www.youtube.com/watch?v=hCBvofd2aF4. For an in-depth look at the printer with this Z axis support in place, I invite you to watch the video at https://www.youtube.com/watch?v=_6gyYRbOJZ0. The distance between the rods on my setup is 22 mm, and they feature 8 mm diameter threaded screws and support rods. A standard 608 ZZ bearing is utilized to support the Z axis. The supports themselves were printed using PETG material, with an extruder temperature of 240°C and a bed temperature of 65°C, at a layer height of 0.2 mm. You can refer to the screenshot for additional print settings. I extend my gratitude to Sebastian and Guido for their assistance in constructing this custom Z axis support. Update: I have since incorporated a new version of the support with an integrated switch holder, which is showcased in the video accessible at https://youtu.be/yk4AJZu5WKU.
