Easy Print Prusa Z Couplings

thingiverse

My friend and I assembled a Prusa using Clonedel components, encountering reliability issues with the z-motor couplings connecting to the threaded rod lead screws. We attempted to print available designs but our printer was not functioning well enough. The simple geometry of these couplings allowed printing on our basic machine. Although not efficient in terms of material usage, they perform the task effectively. To install, simply print and bolt them on using nylocks or double-nuts; failure only occurred when single nuts were employed. The provided trig diagram aids in understanding OpenSCAD parameters, with the .stl designed for 5mm motor shafts and 5/16" lead screw threads.
