Ikea Lack Enclosure Door Knob remix for 20x6x3mm rectangle magnets with top stopper

A remix of the door knob for the Ikea Lack enclosure, adjusted for bigger magnets, smaller knob, and with a top stopper. I basically redrew the part, with the following changes: Adjusted magnet slots to 19.75*5.7*3.2mm (my magnets were sold as 20x6x3mm, but slightly smaller than that). Made the knob smaller. (I didn't like it that big.) Added a top stopper with magnet slots so that the door is held better when closed. The stopper matches the smaller clearance between the door and enclosure. Countersunk the screw holes. I tried to keep the same footprint, so it can be used on previously drilled holes.
