Torture Spider, 3D-printer torture test - overhangs - cooling - retraction

Edit 2019-02-26: Simplified version with reduced overhangs on legs. What a Challenging 3D-Printer Test. Highlights Cooling, Overhangs, Stringing, and More. Can You Beat It? (Made for a 0.4mm nozzle, smaller nozzles have an advantage.) Why I Created This Model I designed this model to test optimal layer heights for overhangs and verify effective cooling around 360 degrees with my cooler. Print Recommendations Maximum Cooling is Key! Best results on overhangs are achieved at layer heights between 0.12mm and 0.16mm. Use two walls, no infill, and a brim if you don't have great bed adhesion. Understand and Improve Your Results - Maximize cooling for even results. If some legs look bad while others look good, your cooler may not be cooling evenly or it could be related to settings. - Experiment with slower speeds and lower layer heights to improve overhangs, but avoid going too low as it causes curling on difficult overhangs. Find the Best Retraction Settings Start at 0mm retraction length and increase by small amounts until stringing stops improving. Then try different retraction speeds and lower temperatures if possible. Share Your Results Post pictures of your best prints, including printer model, cooling mods, and nozzle size. https://youtu.be/AnPs7Sz5uAk
