This is Instagram camera icon.
You can see this icon on the notification bar of your smartphone.
I would be happy to see this icon on the notification bar of my smartphone. So I made the 3D model of it.
This model have a hole for strap. A original size is 40mm∗40mm∗25mm. The logo is on the back.
I added two models.
These are thinner versions for easy printing.
A height is 10mm. (Part of lens is 12mm height.)
