Simple coil base for metal detector.
Diameter 200mm, it is Anet A8 limitation, not too much, but can be customized if you have something more than I do.
Printed out of PLA
20%
0.4 nozzle
Supports are required for upper edge of the coil.

Printing time - about 9hours.
I'd prefer to make hinges a bit stronger, probably 8mm of width should be enough, but I will not reprint it :)
Just keep in mind to modify scad file if you are going to make one.
