This is an imperfect model of the human thoracic vertebrae T1-T12. Each vertebra is printed in two halves and can be superglued together.
It is a work in progress. Several vertebrae don't fit together perfectly, the costal facets are invisible, and the intervertebral foramina are closed down. That said, it is useful for learning osteo/arthrokinematics of thoracic spine movement and it combines with cervical and lumbar/sacral models that are available on Thingiverse to make a really neat, life-sized spinal column model (photo shown; model is hanging in the Richardson Library at DePaul University). I used modeling clay as intervertebral discs.
I would love it if someone fixed the issues listed above and remixed this model.
The vertebrae print fine at the lower 0.8 mm resolution as well
Creating a spinal column from these files and others
These thoracic vertebrae models were created in Meshmixer from scans of plastic vertebrae from a human skeleton model. Scans were created on a Matter and Form 3D scanner and modified in Meshmixer.
To make the spinal column shown in the photo, I superglued the halves of the vertebrae together and used modeling clay for intervertebral discs.
Cervical vertebrae were from this model by bdario91: https://www.thingiverse.com/thing:2303910
Lumbar vertebrae and sacrum were from this model by dantana: https://www.thingiverse.com/thing:781206
Both of those models print great, and the scale/size of all three models is appropriate to print the entire spinal column from those two models and this one. These thoracic vertebrae are rough by comparison to bdario91 and dantana's cervical and lumbar/sacral models, but they complete the spinal column.
