One entry in a line of eyepiece cases I'm working on to encompass my whole eyepiece/lens collection. This case is built around the Celestron X-Cel LX 3x Barlow Lens. It's a very tight fit (by design), so it's unlikely it will work with any other lens, even in the same series, but if people are interested, I'll be happy to share the .step so people can modify to suit their needs - or if you ask nicely and provide detailed measurements, I can whip one up for you!

The case is intended to be printed with PETG for the primary case and cap. The remaining pieces are intended to be printed in TPU, and are added as liners to the main hardshell case. This 2 layer system is intended to provide a reasonable degree of shock absorption and fall protection to the case.

This case is a bit awkwardly wide due to the need to accommodate the tightening screen on the lens. I'm open to suggestions for other ways of accommodating it while keeping it slimmer.

The screw threads on the bottom of the cap are there so that each case can screw into a carrying case that I'm going to post later for ease-of-transport
