First things first, this is the test model I've done: (Previous link) Edit: Removed link since the model has since been removed.. I don't have the time nor money to do test-prints and I'm having trouble visualising how big it would actually turn out only seeing the model. I downloaded another pendant's model for size comparison but I'm still not sure, are there some good size guidelines to follow? I wanted the design to be simple, but is it too simple? I was thinking of doing a small series of similar simple pendants. Is the hoop for string/chain unneccesserily big? I want it as small as possible but still functional and strong so there's minimal risk of breaking. Is all the thicknesses alright? I've seen some pretty thin designs but stainless steel is listed with a minumum wall-width of 3mm which the counter-relief part around the lightning doesn't clear (1.5mm) which has me worried. Any other general feedback is greatly appreciated too .
