Excellent model. Minimal errors, unlike the full lumbar hip and spine model that has thousands.  

Even so, it does not preview or print with Simplify3D due to residual errors I could not repair. Prints well with Makerbot Print.  Cura does not support Replicator+ so I don't know if it prints there.

Would have been five stars if I could print with S3D.

Did 75% scaling to fit my Replicator+. 15 hours.

Needs supports which are numerous.  Time consuming to remove because of all the cavities. Well worthwhile to do. Felt like whittling on the porch.

great model worked well.

I sliced it with LUBAN (Snapmaker) and it took 4 days to print because I set the resolution to 0.1 mm to create a beautiful surface finish.

Removing all the supports was not an easy task as some supports were hard to reach and also I had set the support thickness too high.(my mistake)

I will have my L4-L5-S1 operation soon and it helps me visualising the upcoming surgery.

very happy with the result
