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.
