Magnet Insertion Tools

thingiverse

I rely on an assortment of 3mm diameter x 3mm height cylindrical rare earth magnets to keep 3D-printed puzzles and models firmly assembled. Unfortunately, these magnets can be tricky to handle – their small size makes it difficult to grip them comfortably, and often requires considerable force to insert them into the model's pre-drilled holes. These innovative tools have made a significant impact: include a recess with a diameter of 3.2 mm x height of 3.2 mm in your CAD design. Load the "+" or "-" tool with a magnet (ensuring correct orientation for it to stick securely). Add some JB Weld epoxy to permanently secure the magnets inside their holders. Utilizing the convenient handle, easily insert the magnet into your model's cavity. Once done! Developed as part of 'Motivating First-Year Calculus with Robotics', a National Science Foundation-supported project under grant DUE-12-45540.

When assembling the set, remember to orient the magnets correctly – ensure they adhere properly if inserted accurately in their respective holders
