C7 aka Figure 8 power connector

thingiverse

I needed a dust plug for something I was making. The item has a C7 power plug. I couldnt find anything so... after about 6 iterations this is my final working plug. The holes are not perfect circles, this is so they snugly fit the prongs in the plug. It is best printed at 0.2mm layer height in the orientation it is in. You can print in other orientations but I found that it didnt always fit right unless printed in this orientation.
