Full Size Anatomically Correct Human Foot Model

This anatomically correct human foot model uses 2.85mm filament to attach and hold the bones together. The filament allows for some movement between bones, however excessive pressure or repeated movements may weaken and break the filament. This model is designed for displaying, studying or light use, but will not stand up to rough classroom handling.

EDIT (October 10, 2021): see "remix" section for pictures and suggestion by user "3Dmonios": "I had no 2.85mm filament so I used a 3mm PTFE tube to join the pieces together. It worked very well."

This is an advanced project to print and assemble. Some anatomy knowledge is helpful but not necessary. Regardless, you will be an expert by the time you are done!

Every attempt has been made to maintain anatomical accuracy with the following exceptions. The sesamoid bones have been fused to the first metatarsal, and the proximal bones have been fused together. These bones are too small and fragile to be printed and articulated separately.

Printing Instructions

A file of the complete foot model is included for reference only.

Raising the bones off the print bed around 3mm and adding support helps to maintain the contours. “Tree” supports in Cura works well.

The metatarsal and phalanges are positioned from left to right: fifth (little) toe, forth toe, third toe, second toe and first (big) toe. Keep track of these as you print them! It might be helpful to leave the support structure on until right before use. Labelling them might be helpful too.

There are two versions of the calcaneus: a plain one and one with hole to attach to the optional stand. Print the one you want.

Assembly Instructions

See above for a picture of the pathways of connecting filament through the tarsal bones. You will need to use a very strong glue; CA glue works well. Always to dry fits before gluing and be sure to trim the filament to the proper length before the final glue. Allow time for glue to dry between each step.

1. Connect the calcaneus and tarsal bone with one 25mm and one 10mm segment of filament. Glue in place.
2. Thread two long sections of filament through the navicular. Start with 80mm for the medial hole and 40mm for the lateral hole. Connect the two filaments to the tarsal bone and glue in place.
3. Attach an 80mm filament to the lateral aspect of the medial cuneiform.
4. Thread the middle and lateral cuneiforms on to the medial cuneiform and attach the three cuneiforms on to the navicular.
5. Attache cuboid on to the lateral cuneiform and thread a 60mm filament through the cuboid into the calcaneus.
6. Insert 10mm segments of filament into the remaining holes of the cuneiforms and cuboid.
7. Thread an 80mm segment of filament through the proximal ends of the second, third and fourth metatarsals.
8. Attach the second, third and fourth metatarsals on to the cuneiforms and cuboid.
9. Attach the first metatarsal.
10. Attach the fifth metatarsal.
11. Attached the phalanges.
12. Attach the tibia and fibula together to the talus with 4 segments of 25mm filament. Ensure that the tops are level and properly positioned. You are finished!

By now you should be able to get advanced standing in a university-level anatomy class! I hope you enjoy this model and can post pictures of your finished project!
