Left Foot Bones Anatomical Model

UPDATE 8/7/2026: top z distance should be 0.2 not 2!

This model represents the bones of the left foot and ankle generated from a computed tomography scan. It is life size so it fits better on a printer like the A1. Each bone is clearly distinguishable including sesamoid bones--I added just enough connections so the whole thing would print in one piece.

Original model was made available on the NIH3D Print Exchange by user MySegmenter under CCBY license. I separated the bones of the left foot and leg from their full skeleton model, remeshed the bones to optimize them for printing, added connections where needed to print in one piece, and cut the tibia and fibula around the distal ⅓.

Printing:

• 0.20 mm layers

• 2 walls, 10% grid infill

• tree supports at 30%

  • top interface layers = 2

  • top interface spacing = 0,

  • top z distance = 0.2

  • optional: increase initial layer expansion to 5 or more if you think adhesion might be an issue for your trees

My print is shown with Sunlu matte bone white PLA--matte PLAs make supports much easier to remove. I printed in essentially anatomical orientation since most of the bones are angled anyways in this orientation. This also confines the support surfaces to the bottom. The foot sits upright just fine without a base so I didn't bother making one. 

Great reference for a doctor or osteology and anthropology classes for learning your foot bones!
