A simple guide for Prusa i3 hotbed wires.Print the uploaded STL file (a smaller/simpler version is also provided). Use OpenSCAD file if you want to make any modifications.I recomment to print the Thing rotated 90° on one of its SIDES in order to give more robustness to the clip. However printing can be tricky, as support material needs to be created (I used Slic3r 0.9.8, PLA, 0.2mm slices... no problems). If you have problems with support material then print it rotated 90° on its BACK.
