Notes:

I used abs and therefore a 20mm brim to hold it down

The magnets are 10x2mm and they do a good job of holding it, however you may need to file the top of the magnet area down as i did to get it to fully close.

if you do print in abs, the top and bottom are "glued" on with acetone. the bottom you see is a couple of bux at walmart and will weld the parts together so make sure you get it on right the first time.
