My thing http://www.thingiverse.com/thing:1563812 was a really quick and easy 3D-printable screw-in front lenscap design, set-up as a customizer application. This enhanced version not only supports everything that did, but also allows creating custom screw-in filter holders. Basically, this can now make screw-in versions of the solar filters my thing https://www.thingiverse.com/thing:2475342 made as bayonet-mount for the Canon SX530 HS. The two-piece design sandwiches AstroSolar film to make filter -- just as was described in my instructable about the SX530 HS filter: https://www.instructables.com/id/Safely-Shooting-the-Sun-With-the-Canon-PowerShot-S/ Print Settings Printer Brand: MakerGear Printer: MakerGear M2 Rafts: No Supports: No Resolution: 0.25mm or finer Infill: at least 25% Notes: The solar filter material we recommend is AstroSolar Safety film, http://astrosolar.com/en/ , which is a 0.01mm thick material. It doesn't matter if it has little waves in it as mounted, but you don't want to stretch it. Thus, print the two pieces, make sure they fit reasonably (remove any print defects such as stray hairs), and then spray contact cement on the side of the threaded half that was printed facing down. Once that has partially dried, simply press that onto the film. The film can then be trimmed to the edge of the part. Finally, the second part is fitted over the film and a soldering iron is used to permanently weld the two pieces together. This is essentially the same process described in https://www.instructables.com/id/Safely-Shooting-the-Sun-With-the-Canon-PowerShot-S/ Note that the 20170816 version is now replaced with a 20170820 version that has thicker sidewalls on the grip for larger-diameter filter holders. The earlier version is still perfectly usable, but the extra rigidity helps. Category: Camera
