Chain hanger for bicycle

Chain hanger for a bicycle seatstay to make wheel removals easier. Bikes used to have these included as part of the frame. Has a slot for a small zip tie. Suggest printing in PETG and using a little of a removable adhesive such as E6000. 2 sizes, small for traditional tubing sizes and a larger one for heavier diameters. Can scale a bit if needed for a better fit. About 1mm smaller in diameter than the tube will make it snap on nicely. Place roughly 10cm from the dropout.
