Been using my 3D printer for a couple of months now and got to making this. They are 6" x 1.5". I currently have two versions. One where the magnets are embedded in the print and another where they are exposed to the back and provide a bit more gripping power. Pricing is $20 shipped in the USA. Please private message (click on my username and select 'private message') me with your order request and to work out any details if you would like one.
