Super Simple Magnetic Pen Holder

thingiverse

Want to stick a pen to your fridge? This will fit most standard pens and will print without supports in under 20 minutes. There's a little bit of springiness to the clip, so it will grip the pen gently to stop it flying off when you slam the fridge door having just realised that you have run out of beer / milk. There's a ready-made hole (if indeed you can make a hole), which is designed for a 10mm (diameter) x 4mm (thick) magnet. This is my go-to "chunky-monkey" size for when you really want something to stick. Unless your pen is made of solid gravitanium*, your pen will not slide down the fridge on to the floor next to the spiders. * gravitanium does not exist (yet). If you do have a pen made of solid gravitanium, well done.
