Simple two parted case for fine accurate tweezers (designed for bend stainless steel tweezers for miniature making with number 7, I do not know how to specify it more. See picture for visual reference.) The case uses two pairs of D6x1 mm neodymium magnets for closing. Glue those in with super glue. Mind their polarity! 

Printed out of PLA without supports on regular 0,2 mm profile.
