Sliding Y-Endstop Mount for Prusa i3

thingiverse

This sliding Y-endstop, designed for Prusa i3 type 3D printers, attaches to the rear or front short threaded rods. The endstop mount is composed of a fixed base and a movable arm with an adjustable switch placement. Key parameters include rod diameter, spacing, slide length, and orientation. Installation occurs without disassembling rods - first click into lower rod then rotate to upper rod. Secure hold can be achieved by clamping between screw nuts, though this requires Y-frame disassembly. The design includes standard 20x6mm micro-switches with pre-drilled screw holes and an M3 thread option. Fully parametrized SCAD files provide STL options for varying arm lengths and orientations; compatibility exists with other endstop sliding arms. Recent updates include a slide cage offset by 10mm for direct placement above rods, and lowered/repositioned slide cases for low-platform printers.
