The rocktopus

https://www.thingiverse.com/thing:5518084

The rocktopus is one of many variations of the thinverse octopus modle, being single print. The amount of variations of the roctopus itself is rather large on the site. This is the version with the sprite glasses designed as a keychain.

The glasses were too flat, and were mangled upon printing. The rest of it turned out fine though. The way the tenticals work is by having gaps in the print so the peices dont stay static, while having joints to keep them in place. There is a bar running through each segment of the octopus tenticals, with a gap of space behind it. The other end of the segment (save for the tips) features a circular clip thing that holds onto the bar, and can move around the bar to get some angles verticaly and horizontaly. Over all, a pretty cool design.
