This was a work I've done for my new glasses. Maybe somebody else loves it.I've used magnets for the case and I still need to get it smoother over the magnets.
CASE: - inside case is not included - picture for engraving is not included
Holes are for case:
Size inside:147mm long and 47mm width and height is 26mm - minus the place for the magnets
I've anodized it with 20-110V from the middle to the outside I've engraved it with a CO2 30W laser - the only I had at this moment.
Sunglasses holder for Rigards RG0105ti in titanium: (As a free addon if you have such eyeglasses)4 holes: 2.15mm diameter and about 1.5-2mm deep
keep in mind that 3D printing in titanium can be expensive!
