This adapter is designed to attach a DSLR to a telescope. There is a slight taper at the end to allow a snug fit. The adapter prints pretty well but I found the supports that were generated in Slic3r to be difficult to remove. With the help of an X-Acto knife, pliers, and a rotary tool I was able to make the slots pretty clean. This is originally designed for a Canon EOS XS but it may work for other DSLR cameras as well. Feel free to comment below with your camera model if it does or does not fit. Thanks for printing!

Edit: JTonerll suggested printing on its side as it made for cleaner threads and the supports came off better.
