These are different wire clamps that can be used to hold the wiring for an electrical project. The flat clamps come in different center section widths. I had the best luck printing these on a raft as shown in the pictures above. The clamps easily snap off of the rafts and they keep them all together so work well all around. The files are for one clamp so use Cura or your slicing program to print any number at once that you need. You can find the files to print this on my thingiverse account ( HERE ). You can find all the files to 3D print this object and others on my thingiverse.com account ( HERE ). Here is a link to the info of the clamps on my site..... http://1fatgmc.com/RailRoad/3D-Printer-2/page-54.html Sumner
