Magnet Insertion Tool

This magnet insertion tool allows you to ensure that all the magnets inserted into your project are the correct polarity. I printed one in red and another in blue and use the red to insert magnets for the main print bodies and blue for magnets going into the attachments (the parts that attach to the body). Just glue the magnets into the ends and make sure that the magnets for the red and blue have opposite polarity and are attracted to each other (N on red, S on blue, etc).
