Every year there's a Folsom Street Festival in San Francisco, CA. It's an event where folks put on their favorite weirdo outfits (or go nakey) and make a spectacle of themselves. I would be remiss not to join in they fun so I grabbed my girlfriend's spikey collar from when she was in high school only to find out that it was way too tight around my meaty neck.

Since we had about an hour before departure to the festival, I quickly designed and printed out this collar extender so that it would fit. Just slip the end of the collar between the grippy parts and make sure the hole lines up with the détente before latching the other end of the extender through the buckle. After just one re-design, it worked out quite nicely, I must say :)

If you found this useful, it would bring me great joy to see your work - so be sure to share. :)

Or, better yet, please feel free to dump a bitcoin or two here (I'm trying to collect as many as I can before the apocalypse):

... include a note to the effect of "Hi 3E8, thanks for the collar extender thing... my life is infinitely better on account of it and please accept this small handful of bitcoins in gratitude".

You're welcome! (in advance) :D

Also, feel free to peruse my other submissions which are almost as varied as they are many:
