Prusa i3 Z-Axis support brackets

thingiverse

The Prusa i3 frame is missing essential support at the top, which may lead to undesirable oscillation or vibration during a print operation.\nAs an added feature, here's a comprehensive set of brackets that provides secure support for the Prusa i3 frame to the Y-Axis threaded rods.\nYou can refer to this YouTube video for step-by-step instructions on implementing this setup.\nI've also included versions with 6mm diameter, perfect for smaller threads.\n\nInstructions: Print your parts at a resolution of 0.3mm and set an infill level of 30% for optimal results.\nThe mounting holes for the top bracket align perfectly with existing z-axis linear rod support openings, so you won't need to perform any tedious re-drilling.\nAll you'll require is a longer M3 screw - preferably around 25mm in length – to cover the extra travel distance created by this new setup.\nOn the bottom side, ensure that you extend the 10mm threaded rod an additional 200mm to allow sufficient room for both sides of the frame to secure the lower bracket properly.\nThe connection between the top and bottom brackets calls for a robust thread. Choose 8-10mm threaded rods measuring exactly 350mm in length, and secure them by tightening the nuts firmly on either side.
