Vertebra CP

Crease pattern for my vertebra model: Lumbar Vertebra

Built on a 16x16 grid, if you collapse the base, it comes out pretty boxy. The rectangular box that would eventually be the vertebral body is 2x1.5x1.5 squares. I truncated the corners of this rectangular box to round out the top/bottom views. The pleats at the top of the square wrap around and tuck into two triangular slots inside the box.

Flap-wise, this crease pattern includes 3 flaps per side:
Spinous process: long flap pulled from the lower corners of the square. The two flaps wrap around the foramen and combine via improvised tab-slot
Transverse process: pulled six units up from the base of the square at the sides
Superior articular process: a middle flap embedded in the transverse process flap
Posterior articular process: technically not included here due to it being less prominent in some vertebra. I used a elias stretch on the long spinous process flaps to get a 1 square long flap for this.

I've tried folding the thoracic and lumbar vertebra from this base; I preferred the lumbar.

This is what the crease pattern collapse looks like: imgur.com/a/mYghu
In the last image, the flap assignments are:
Bottom two flaps: spinous process, these flaps come together
The two short stubby flaps right above that: are actually two flaps embedded inside each other. outer flap is the transverse process. Inner flap is pulled out to make the superior articular pillars
The rectangle above that: vertebral body
The rest of the pleats above that: extra paper that is wrapped around and tucked inside the body to enclose the vertebral body.
