relay testing cable holder

this is to hold protection relay testing cables. there are 4 N42 12mmx3mm captive magnets that are inserted at layer 195. i designed this to comfortably hold one set of current leads, one set of voltage leads, and two sets of two wire leads (for control power and one input) that come with an SMRT 46. the N42 magnets are only strong enough to hold the current leads and one set of two wire leads on my fridge. they either need to be bigger or stronger i don't know yet. back to the drawing board.
