Wrenches for Large Threaded Bolts

thingiverse

My nut got stuck while wearing in the threads. Luckily I had a 3D printer so that I could print the remedy! I am sure that this have and will happen to more of us, so here you go, fitted wrenches! The inside dimension is 47,5 mm to give a snug fit around bbuonomos bolt and nut found at http://www.thingiverse.com/thing:4880 I have included the Solidworks part files as well if you want them. UPDATE 1: After printing and testing the first wrench I redesigned it and now it prints in less than half the time, and looks cooler :D Instructions First count the sides on your bolt, I didn't and ended up printing the wrong wrench at first :) Download the appropriate file and print. I used 1.2 mm walls and top/bottom because I like strong tools. With thick walls like that, I see no point in going above 20% infill. File selection guide: 47_5_8sided_slim_H_10mm - Probably what you want, quick and nice looking. 10 mm high. 47_5mm_8sided.STL - A larger and earlier version of the wrench, 20 mm high, takes a long time to print. 47_5mm_6sided.STL - A hex-wrench for traditionalist, as of now it WON'T WORK with the "Large Threaded Bolt and Nut by bbuonomo"-thing since it was 8-sided last time I saw it :)
