Prusa i3 Z Axis Brace
SummaryThis is for the "Original" Prusa i3 kit from Prusa Research. When the Y axis on the printer makes rapid moves it causes a vibration that then causes an oscillation in the Z axis. Hanging 1KG of filament on top of the printer just makes it worse. This brace attaches to the bottom rod on the back of the printer and ties it in to the top of the Z axis thereby reducing the oscillation making for a more accurate print. The idea is similar to the two items below, but differs in that the power supply on this design is attached to the side of the main frame obstructing the rod design that extends out for the original base and serves to allow for extra clearance at the back of the Y axis. http://www.thingiverse.com/thing:319018http://www.thingiverse.com/thing:338111Print SettingsPrinter Brand: RepRapPrinter: i3Rafts: NoSupports: YesResolution: .35 First layer, .26 all othersInfill: 40%Notes: Printed the base in PLA and the top in ABS, but either would work fine in this application.
