This three-quarter size spine model is assembled using 2.85mm filament, allowing the vertebrae to flex and rotate. An optional display stand is available. See here for assembly video: https://youtu.be/PJFxQbMtud0
This model is designed for display purposes. While the filament allows for some movement, the movement is not biomechanically accurate. See here for a more challenging but biomechanically accurate full size spine model: https://www.thingiverse.com/thing:4801717
With the exception of C1 and C2, vertebrae are numbered on the posterior aspect of the vertebral body. The numbers are to assist with assembly and are hidden in the final assembled model. There was only space for numbers, so you’ll have to learn what C1 and C2 look like and be able to differentiate between cervical, thoracic and lumbar vertebrae. (It’s not that hard!)
Every effort has been made to maintain anatomical accuracy; however some small modifications were necessary to optimize the files for printing. In particular, the bone around the transverse foramen in the cervical spine, and the articular processes and lamina of the cervical and upper thoracic vertebrae have been thickened.
Holes have been added for the insertion of filament, and small nubs have been added to the inferior surface of the vertebral body to ensure proper spacing.
The modifications are not noticeable for display purposes, just don’t use this model to plan your next spinal reconstruction surgery.
