Improved X ends for Prusa with clamped rods

thingiverse

An improved version of Prusa's older x-ends design is introduced, which uses two screws per rod for a robust fixation. However, iteration 2's press fit and closed ends solution made disassembling the x axis difficult, so the author came up with a new design. To save time, modifying an existing file was avoided, and a completely new design was created that includes additional upgrades like clamped LM8UU holders. The rod fixation in this design uses one screw per rod, tightening built-in clamps for a rock-solid fit and easy adjustability. Screw heads are accessible from below, and nut traps are present at the top. Open end rod holes allow rods to be pushed through entirely. The leadscrew nut trap design eliminates post-print processing by using two bridges instead of a circular hole. The design is parametric, allowing for professional lead screws like trapezoidal ones with bigger nuts. STL files are available for metric trapezoidal lead screws TR8x1.5 and nuts of 17mm wrench size (15mm height). For standard Prusa requirements, use the "threaded rod" files. A reminder to drill through support layers inside the M3 rod clamp holes is included in the instructions, and STLs are generated for 0.25mm layer height, adjustable in OpenSCAD.
