Tired of fumbling with unmarked magnets?
This 3D printable pen lets you create a customizable magnetic tool with selectable north and south poles. Print the main body and separate caps, then simply insert magnets in the correct configuration.
Here's what makes this pen great
- Modular Design: Print the pieces and assemble them for a clean look.
- Double Duty Caps: Labeled "S" and "N" for easy polarity identification.
- Colour-Coded Options: Print the caps in different colours (red = north, blue = south) for an extra visual cue (standard colour scheme recommendation).
- Adjustable Strength: Each cap holds one or two 8x3mm magnets, allowing you to customize strength.
This pen is perfect for
- Educators and students for science experiments
- Makers and hobbyists for various magnetic applications
- Anyone who needs a handy tool for manipulating magnets
Printing
Print the 3 pieces, one of each
- caps north and south can be printed in different colours to help identify the polarity visually
Assembly
- Insert one or two magnets in each cap in the correct orientation
- To help you identify the correct magnet polarity, you can use the app PoleDetector (follow app instructions to find magnet polarity)
- Insert the caps on the main body (the pieces should remain in place due to press-fit, but you can you a drop of superglue to keep them in place
