Description
SummaryThis filter wheel can be used for 9x1.25 inch filters or 5x2 inch filters. It has Female T2 thread on both sides. This is an improved version of the 9-position filter wheel (thing 1329038). It's equiped with spring-loaded ball bearing click stops which provides a better and more stable positioning of the filters. A stainless steel spring (7.5 mm diameter and a length of approx. 20-25mm is used. It's also a bit bigger (174x174 mm) but can house a 9x1.25 inch or 5x2 inch filter wheel. There are a few accessories included (1.25 and 2 inch nose piece, brace and T2 male-to-male adapter).Print SettingsPrinter: Vertex K8400Rafts: NoSupports: YesResolution: 0.1Infill: 40-50%Notes: Not all items need support. Glue the spring arrangement into the reserved space of the front plate. I used superglue. Use M3x20 screws/bolds and M3 nuts to bolt the whole thing together.

Great to hear that this design has inspired you.
Please be aware that I would not recommend attaching any heavy optical equipment to this filter wheel (when using PLA or ABS) as this will result in bending of the front plate and thus a shift in the optical path.
Looks very nice. This and your eyepiece turret are very nice in themselves, but they get me thinking. When mid-August comes, (after the Nebraska Star Party), I can see myself working on something that uses some of your designs. I'm trying to figure out an eyepiece/filter/camera/focuser system that could be fully remote controlled from a nearby tabletop (or further away). I use one of those huge truss type dobsonians, want to do photography, and don't want to change my mount. Consequently, I'm even thinking about eyepiece/camera rotation to compensate for the view rotation that the mount produces. I'm still brainstorming but your designs are good food for thought. :-)
