Customisable Opal Case (Oval gems)

thingiverse

This is based on https://www.thingiverse.com/thing:1563872/files but adapted for printing Opal cases. The default opal case above is for a 3mm X 5mm Opals. Very small and usually not worth having an expensive case for it. But is still very worth giving as an interesting Australian gift. You can adapt it easily for more expensive and larger Opals. ---- Note: I found it slightly hard to close, also with PLA the hinge tends to be quite brittle. Would be interested for some ideas how to deal with this. (I think you are ment to use PETG instead? That's what the parent design used...) Okay on further investigation... the key factor is height. As the default height is way too small, leading to the hinge being too small. So I re-uploaded to have higher height.
