PCB mounting bases

These are PCB mounts in various heights, for general use as fixings where appropriate. They are intended to be attached to a case or surface using double-sided tape or suitable adhesive. They take M3 screws, though easily drilled out for similar size UNC or BA. The set includes three heights with a circular recess on the underside, intended to have a suitable length screw fitted from underneath, plus one short type that has a hex recess on the underside which can have an M3 nut pressed in, so a threaded pillar or stud / threaded rod can be screwed in from the top. They will all also accept an M3 screw simply screwed in from the top, though that is not as solid as when a metal screw or nut is used. As printed, they have support for the underside recess - that can easily be removed by tapping a small drill or rod with the part over some plier jaws. The easiest way I've found to fit a nut accurately in that version, is to thread it just on the end of a long screw and push or tap that
