About this 3D model

[UPDATED TO V3] - Reshaped design - Added a second model (magnet lip) with a slot (instead of a coin or paperweight) in case you have two extra 3x6mm cylinder magnets. I've fit mattarang's attempt parametrically to the standard bottlecap diameter of 28.5mm and space for a magnet of 3mm x 6mm (with 0.3mm space to correct for extrusion width). As a bonus I've beveled the edges. Be sure to print it flat on the printbed and use close to 100% infill as 30% reportedly breaks at the thinnest point. You can buy the magnets from ebay for under $1 for 10. http://tinyurl.com/m586ry3 This is a work in progress to discover more about the Structural and Legal weaknesses in 3D printing.
