This is a remix of the Lothlorien Brooch by PLOKR on cults (see original below). I removed the wire from the model and added a hole in the bottom for space to glue a safety clip, so it can actually be worn. I split the model into three parts, so you can assign the colours to the individual models, however I also included the single model in case you find it easier to paint the model in the slicer. It may be a little difficult to align the models, however if you use the ‘base’ as the parent model and add the ‘top’ and ‘green’ as submodels you can raise them up off the build plate. 

I printed with a 0.2mm layer height at 100% infill. For the wire, I cut a few lengths of filament, bent them into the correct shapes and glued it to the print. A lot of safety pins have a hole in the top that you can feed the filament through to keep it contained. I find this to look much better than the original model, which included the wire as part of the print.

Hopefully this pleases some Lord of the Rings fans!! I gifted the one in the image to my friend for their birthday and they loved it :)
