8" Metal Detector Head

thingiverse

Problem: I am building a PI Metal Detector with an 8 inch head ring. I want to print a ring holder but my printer will not accommodate an 8 inch ring. So here is my solution. All parts are snap to fit except the pivot. It needs two screws to hold it to the shaft and one larger plastic bolt to hold it to the bracket. I am posting this as a starting point for anyone who wants to try this. Having assembled it I realize it is vastly overbuilt and could probably be done in two halves rather than quarters, but it works for me. I will probably refine the design and post a follow up shortly.
