Every shop seems to have the same issues, the lost 10 mm socket, the broken tap, and the dozens of misplaced pens. We were getting sick of never being able to find a Sharpie so the Magnetic Pen Holder was born. 3D Printed out of durable PLA+, there are two powerful 5 lbs. magnets inlaid into the holder so you can stick it to your Portaband table, your shop press, or your welding cart. Room for 4 markers and 3 pens, there's plenty of room for all your different writing implements. This is one of those add-ons that you don't realize how badly you need until you start using it!
