https://www.youtube.com/watch?v=MITcD5aHg9w *NEW* Updated assembly video for v2 version! https://www.youtube.com/watch?v=npht68N1uzs *OLD* Check out my video on assembly! Original design incorporated a shackle and ball bearings from a broken Abus 72/40 and now features an option to 3D print those parts instead. They come in 2 halves and will have to be glued together. If printing with ABS, then you can weld them together with acetone. *Design currently requires 6 springs in order to function properly. Springs can be harvested from cheap clicky pens* Print all parts without support except for the Body & Key. Supports touching buildplate only. Turn on coasting if you can to reduce z-scar on parts. All parts can be printed at 20% infill except for key, top and bottom retainer plates, shackle and ball bearings(print at 100% infill instead). Optionally, Pins and Pall can be printed at 100% to increase wear resistance. Find me on Reddit (u/LethalogicaX) if you have questions, comments or suggestions. Feel free to remix this and improve the design! Current Issues: -Body has some round overhands that are difficult to support and will not print properly unsupported. You can still print it without support but there's some post-processing involved to clean up the first few layers of the overhang. -Key requires pristine tolerances in order to move the pins correctly. Supports tend to leave some junk on the bottoms of the bitting surfaces that require post-processing in order to get a smooth operation
