This model is based loosely on the Canon 7D Mark II DSLR camera, but is generic enough to match most Canon DSLRs.
The earrings come as a pair (2 pcs total) and are fairly light-weight, weighing about 3.5g each (~1/8 oz). Weight varies slightly by material. They are hollow inside and open at the bottom.
They have a 1.6 mm (1/16 inch) loop which is large enough for most any earring hook (not provided). The loop is located such that the earrings will dangle straight. The dimensions below are for both earrings together. The width per earing is about 8.5 mm (3/8").
Though I have not made these, I have made the slightly larger necklace pendant which turned out very nice (my wife really liked it).
These could also be used as charms on a bracelet.
I'd love to get feedback on these if you have any!
