Hartz Dog Flea collar buckle

thingiverse

I have multiple small dogs and as it turns out, one of my 26-inch collars has enough slack to fit two of them comfortably. However, there aren't multiple buckles, so I decided to make a change. To create this new buckle: Print the design off your printer, depending on its skill level with bridges, you may need to file some small ridges in the tiny loop. The center loop is designed to be snug on the collar material, so push one end of the collar through that loop until it covers about half of one of the side loops. Then, use the collar like it came from the factory; when you push the excess through the second loop, it puts pressure on the center loop securing it in place.
