<h3>/!\ WARNING /!\</h3> <p>This project is on the back burner for now.<br/> Someone else pushed the idea to completion, print his thing instead : <a href="https://www.thingiverse.com/thing:3063430">https://www.thingiverse.com/thing:3063430</a></p> <h3> People who have printed this reported some flaws in the design. I have NOT fixed them yet! Print at your own risk.</h3> <p>Optical Filament runout that works even with transparent filaments.<br/> Just print the lever in an opaque filament (black is preferred).</p> <p>Push the lever down and insert the filament. When the filament runs out, the lever springs up and triggers the optical sensor.</p> <p>It uses a M3 screw for the hinge.<br/> Any spring smaller than 5 mm diameter and 6 mm compressed and 10mm expanded can do the job. A spring from a clicking pen should work. otherwise this seems to be a good match (not tested) <a href="https://www.mcmaster.com/#9657K267">https://www.mcmaster.com/#9657K267</a></p> <p>Not tested yet!</p> <p>V1.2 wiggled some holes to prevent slicing issues with s3d (Cura worked fine by the way lol) and added a nub to the lever for the spring.</p> <p>Fusion 360 link: <a href="https://a360.co/2vgCXrf">https://a360.co/2vgCXrf</a></p> <h3>Print instructions</h3><p>Category: 3D Printer Parts</p>
