<h1>5 slots 1.25'' filter wheel for telescope.</h1> <p> There's some fine threads in this part (M42x0.75 and M28.5x0.6) so you need a fine tuned 3D printer. Adding "post stretch script" post processing in Cura helps to print threads in good dimensions.</p> <h2>TO DO FIRST:</h2> <p> In order to avoid waste of time and materials, I've added 2 test-prints to let you tune your printer before print the whole thing and to be assured that you can correctly print the threads.</p> <P>The wheel is assembled with a central M3 screw and a small spacer with 'nylstop brake' nut not too tightened. The cover can be assembled in 3 ways: <ul style="list-style-type:circle"> <li>Use "boitierv2.stl" and assemble with 4x M3 screws, nuts and spacers (simplest).</li> <li>Use "boitier.stl" case and add 4x M3 thread inserts in the existing holes with a soldering iron for example.</li> <li>Use "BoitierV3" (print with no supports) and assemble with 4x M3 screws. Hex nuts will take place in hex footprints in the bottom (best cosmetic). </li> </ul> </p> <p>Keep in mind this is not a metal part, so <b><u>don't stress the threads with heavy parts</b></u> like DSLR or other accessories. This part is designed to fit at the end of the imaging train, and then to support a little lightweight camera like uncooled ZWO ASI for example. You can secure it with a little cord fore more security.</p> <p> The little square window you can see on the face cover can let you know the selected filter, for this you can stick numbers on the filter holder. </p> <p>Hope you'll enjoy</p>
