Prusa i3 Y corner

thingiverse

I just started on my first Prusa i3 build, and while there are plenty of options available for Y corners, I designed these with screw-down caps for the smooth rods. I prefer to design things that make use of 3D printing's capabilities, which is why I added a recess on top of each cap. My design utilizes the standard 1 X M10 rod, which runs along the front-to-back axis, as well as 2 X M8 cross-rod connections and 8mm OD smooth rods. To assemble each corner, you'll need two M3 x 10mm cap screws that are approximately 15mm long; these should suffice. No trapped nuts are required; instead, simply tap the holes for M3 fasteners. As this isn't a high-load or stress point in the assembly, self-tapping screws could also be used as an alternative. This corner design comes with two variations: one accommodates SC8VUU bearings (including both the bearing and housing), while the other is the LP version for standard LM8UU linear bearings.
