J-hook fixation

Very small and fast to print thingy that makes the wire that is attached to a J-hook stay in place and not slip from the small eye into the clip area. This particular thingy is made for a J-hook that measures 2.5mm x 4mm at the smallest place (where it goes as seen in the pictures), but it is easily scaled in x-y (or even x-y-z) to make it fit a larger or small J-hook.   To put it on the J-hook, slip the J-part into the hole of the thingy, then press the lever and slide the thing down to the narrow place as shown in the first picture.   Here printed on an A1 Mini in generic white PLA
