Dog Waste Bag Holder Kit with Chain

This is dog waste bag holder with a threaded top. The cap has a hole for a carrying rope.
I've included the .STL file for printing, and the .123DX (Autodesk 123D Design) file for remixing.

EDIT: I've added the files for a filled waste bag clip, and a chain with swivels to connect the two together. It's a very big print that barely fits on my 5th gen print bed. You may have to split the STL for smaller beds. I've also included the .123dx (Autodesk 123D Design) files for remixing
