About this 3D model
Two simple parts to create a solar filter holder that will go on the aperture on a Skywatcher telescope lens cap (specifically the 200P- may fit others if they are the same size). Cut a circle of solar film, fit into the larger piece with a little super-glue. Glue in the smaller ring to hold in place. Recommended to add a small screw for security (i'll probably replace that with a finger-turnable one at some point) -obligatory safety announcement- *NEVER LOOK DIRECTLY AT THE SUN, AND REMEMBER TO LEAVE YOUR FINDERSCOPE COVERED*
