This is a magnetic pen for assembling magnetic parts, especially on the printer, to avoid magnets being inserted in the wrong direction in some parts

Created this in two possible sizes: 

• One for magnets in the size of 3x2 mm
• One for magnets in the size of 5x2 mm

Be careful to put both magnets into the pen in opposite magnetisation

With this pen it is easy to avoid mistakes by assembling parts which has to be connected.

No Glue or anything needed. There is a pause added just before the place for the magnets is going to be closed.
