New optimized dog poop bag holder and dispenser! This model even has a hook (or clip) for attaching it to the dog's leash, or whatever you like. Fits majority of bag rolls up to 30 mm in diameter. The two small spikes inside keep the bag from rattling around too much.

Compared to my other similar models, this one is slightly thinner and therefore lighter, so it uses less filament and prints a bit faster. The print profile uses tree supports for the hook thing, the supports are very easy to remove.

NOTE: This thing is designed for 30 mm diameter rolls of bags. If your rolls are bigger, you can use my other model for larger bag rolls up to 37 mm: https://makerworld.com/en/models/685846#profileId-614453
