Third Reality Motion Sensor [Magnetic Mount]

A sleek, minimalistic magnetic mount for the Third Reality Motion Sensor. The tolerances are designed so the sensor slides in easily but stays perfectly snug.

Features:

• Two Variations: Includes a standard vertical mount and a "T-Bar" version, which provides a wider magnetic grip for placing the sensor in more inaccessible or awkward areas.
• Friction-Fit Magnets: Designed for up to three 10x3mm magnets to be press-fit directly into the back—no glue required.
• Mistake-Proof Design: Features 3mm relief holes behind the magnets, allowing you to easily pop them out with a paperclip or Allen key if you accidentally insert them with the wrong polarity!

Hardware Required:

• 3x 10x3mm Neodymium Magnets. (I used these exact ones from Amazon: https://www.amazon.com/dp/B0BVY5VYQY)

Print & Assembly Recommendations:

• Filament: Pictured using Elegoo PLA.
• Walls/Infill: I recommend at least 3 wall loops / perimeters so the plastic is strong enough to handle pressing the magnets in without snapping.
• Supports: The standard version prints with no supports. For the "T-Bar" variation, I highly recommend using Tree/Organic supports just for the two horizontal overhangs.
• Assembly: Place your magnets flat on a sturdy desk, align the holes on the printed mount over them, and press down firmly to seat them flush.
