Lumbar vertebrae, derived from the excellent BodyParts3D database. Includes L1, L2, L3, L4, and L5. Sliced in half along the mid-plane so they can be printed easily and glued together.

Journal article describing the BodyParts3D project:


My post describing methods to isolate anatomical features and get them ready to print:



  1. I haven't printed this yet, but the overhang of the inferior articular process looks a bit nasty. Support may be required.
  2. Print both pieces
  3. Glue
  4. Enjoy
  5. Share
  6. Make more body parts, and tag them with "bodyparts3d"! (see links above)
  7. Repeat

Since Zygote body is not open source and that 3Dbody parts proposes only brain parts; it might be time to recreate parts of the whole body in order to create an complete customizable open source library.

Thank you for this model.

I have tried printing this several times but it keeps catching on the overhang about midway causing it to skip steps. Any suggestions on print settings?

I had several unsuccessful prints until I changed my overhang angle support to 60 degrees and then it printed ok. Before I had the supports set right I had the same issue with the overhangs warping upward which resulted in either knocking the pieces off of the build plate or causing it to miss steps. I am using a home built Delta printer using Repeteir Host V1.0.3 and Cura slicing engine.

It has been a while since I printed this... I know that it took a few tries to get it to work. Just in case it may be helpful, I have uploaded the .gcode files that I used to actually print these. I did this on an original Ultimaker. Don't remember if these were from before or after I installed a homemade heated bed.

Gracias, muy bueno!!

Hi! I would like to print your piece! :D Do you have a 3D printer?? or do you know who can lend me the service? If anybody can print it and send me it, I would be pleased to pay.

Wish these were functional.  I could use a new set.
