Magnetic Pen Tool

This is a pen tool that I designed to make organising the magnet polarity with my magnetic board game trays way easier. It uses 5x2mm magnets like my magnetic board game trays. Assemble guide:Print one in blue and one in red.Push one magnet in the blue pen.Put a magnet on the magnet in the blue pen.Push the magnet with the blue pen into the red pen.Now you have two pens with different polarirty!
