Clothes dryer fix - 3mm rod - small but strong

Some clothes dryer rods need a bit of help staying in place. This small and strong thing does exactly this.

Designed for 3.0 - 3.2mm rods/strings and 14mm tubings.

I recommend printing it at a 45° angle (I have made a chamfer for this purpose), with a brim and 4-wall setting. If the rod doesn't fit well, you can try heating it beforehand; it will hold even better.
