This is the NASA file, downloaded directly from the NASA site. "Uplink.stl" is the name given to the file by NASA.http://nasa3d.arc.nasa.gov/detail/wrench-mis Again, from NASA, the ratchet wrench designed by Noah Paul-Gin was uploaded and printed as a working ratchet wrench. The original dimensions - as printed in space - 4.48-inch-long by 1.29-inch wide.The 3D Made in Space Printer is used in a micro-gravity environment with standard additive manufacturing, depositing 104 layers of ABS plastic. ... I have printed five fully-functioning models (see Instructions page). Profguy has moved and you can find other fun items in our shop: http://www.3DBodyJewelry.com Instructions Printed with an ancient Solidoodle 2A Pro using NO SUPPORT on 6x6 bed. Scale is 1:1. Protoparadigm ABS filament, 200/95C. My working models required 0.1mm layer deposit, at 60% infill. 4hr. print-time. Hints: if your bed is anywhere out of level, plum, or square just forget it, fuses into a mess. Printing with a support, raft, or brim only causes melting of the first three layers and prevents the mechanism from working. At a 40% infill and 0.3mm layer a nice (working) model took my Solidoodle about 1.5hrs.
