The footage, originally posted by French blog Nowhereelse.fr. and first spotted by Apple Insider, shows a slimmer iPhone concept with a larger display and a slightly tweaked design.
The mockup is consistent with leaks we've heard about the Phone 6 so far. The volume buttons on the side of the handset are elongated just like those found on the iPod Touch, as opposed to the small round volume keys on the current generation iPhone.
The 3-D-printed model shown in the video claims to show what the iPhone 6 would look like with a 4.7-inch screen, which is among the most popular rumors we've heard about Apple's next smartphone. The company is also expected to release an even larger version of the iPhone with a 5.5-inch screen this year, although some rumors have suggested that this may be delayed until 2015.
Today's mockup is one of many that have hit the Web within the last few weeks. Earlier this week Nowhereelse.fr posted a similar video showing an iPhone 6 concept with a protruding camera.
