NASA Space Wrench - Dissected

This is a NASA file, downloaded directly from the official NASA website. The filename "Uplink.stl" was assigned by NASA. The wrench in question, designed by Noah Paul-Gin, was successfully uploaded and printed as a functioning ratchet wrench from NASA. Its original dimensions are precisely 4.48 inches long and 1.29 inches wide. NASA's 3D Made in Space Printer, operated in micro-gravity with conventional additive manufacturing, laid down 104 layers of ABS plastic to produce this intricate object. I have personally printed five fully-operational models (refer to the Instructions section below). You can find a diverse selection of intriguing items on our shop website at http://www.3DBodyJewelry.com. Instructions This model was printed using an antique Solidoodle 2A Pro without any supports on a 6x6 bed. It was scaled at a ratio of one-to-one, utilizing Protoparadigm ABS filament at 200/95C. My operational models required a 0.1mm layer deposit and 60% infill, resulting in a four-hour print time. Tips: if your bed is slightly off-level, out-of-square, or improperly aligned, just discard it, as the mechanism becomes distorted and difficult to fix. Adding support structures like rafting or brimming only leads to initial layer melting, ultimately preventing proper functioning. Conversely, printing at 40% infill with a 0.3mm layer took roughly one hour and fifteen minutes to complete on my Solidoodle.
