These are simple rings that clamp onto the shafts of the CoreXY mechanism to set travel limits when using the StallGuard feature of TMC2130 drivers instead of limit switches or other endstops. Print two of each to make a set suitable for a Hypercube 300 (10-mm carbon-fiber tubes on X, 8-mm steel rods on Y). Use M3x6 (?) screws and M3 nuts to secure the two halves to each shaft. Modify and re-render the OpenSCAD files if you need different diameters.

The X-axis endstop is 10 mm i/d and the Y-axis endstop is 8 mm i/d; these correspond to the dimensions for the X-axis carbon-fiber tubes and Y-axis steel rods specified for the Hypercube 300. Change and rerender the OpenSCAD files if you need different diameters.
