Chỉ Báo Chiều Quay Động Cơ NEMA

This is inspired by, but not derived from, the indicators here: https://www.thingiverse.com/thing:2638857

Uses a 1/4" x 1/8" round magnet ($0.90 each as of posting) from McMaster-Carr: https://www.mcmaster.com/5862K103/

The magnet press fits into the sleeve, and on many steppers should fit fairly loose in the end hole (made on and works with Prusa motors, tested on a couple others I have around)

Post-Printing =============

Assembly

Press magnet into sleeve and attach to end shaft of NEMA 17 (~40mm housing) motor.

How I Designed This ===================

Layout hexagon grid in Adobe Illustrator (easy to do in Inkscape and Corel Draw as well!) then export to a .SVG file

Import SVG to Fusion360 as a sketch, and extrude the shape, and scale if needed.

Attach (join) a simple hollow cylinder made in Fusion to fit the magnet.

Export (Fusion360 "utilities" tab / MAKE) to STL.

And you're done!
