2" Adapter Extension

This started out as a new adapter design for my filter wheel(https://www.thingiverse.com/thing:3209108), but I needed a simpler something to test the concept. So It became an extension. Rather than using a thumb screw to tighten onto the camera or what ever is next, this tightens evenly from all sides.

If your printer can handle it, bump the print angle up so that there won't be support material on the threads. It will save you lots of grief, especially on the inside threads of the cap.
