I wanted a sharpie holder that held about 6 sharpies upside down (the correct orientation to stop the felt from drying out). There are pockets for up to 5 1/2x1/8" (12x3mm) neodymium magnets in the back. You can glue in these magnets with CA glue. You can probably get away with less than all 5 magnets (we only used 4). This was designed in inches, so if it shows up small in your slicing software, multiply the scale by 25.4 to convert mm to inches. Post those makes!
