Summary

UPDATE 9 August 2013
-refined geometry in the foot and ankle. Some people were troubled with the faceted geometry before, so now it should print smoother

UPDATE 31 January 2013
-Added Ankle and Knee Joints with 4 additional bones (Fibula, Tibia, Patella, and distal Femur)
-Vastly improved Metatarsals
-Corrected Foot alignment
-Talus has been completely revamped from a low polygon retopology from 123D Catch reconstruction of Cadaver Specimen.

There are 26 proper bones in the human foot; 28 if you consider the sesamoids of the 1st metatarsal phalangeal joint complex. That's over 25% of your body's total musculo-skeletal anatomy, hitting the ground every time you go for a walk or run! Quite impressive, really.

This anatomic foot model was designed in Newtek's Lightwave 3D, as part of the podcast @ www.YouTube.com/DrGlassDPM

Anatomic study models can be quite expensive, http://search.anatomywarehouse.com/search?keywords=foot&x=0&y=0 so I wanted to share my printable version with the Thingiverse crowd and give a big shout out to Freeside Atlanta's Hackerspace!

Instructions

Version 2: I've decided not to include individual STL's of each bone. Instead, I've included the Lightwave LWO file, which has every bone (and skin) in low poly. It will be easier this way for me to update the model at a faster rate.

Otherwise, I'd be impressed to see some of the techniques towards printing this and having a clean separation from support material. This (and deriviatives thereof) will hopefully rival things like: molded study models http://search.anatomywarehouse.com/search?keywords=foot&x=0&y=0

Hey this is a great model!

What are the units export in? when I import this model, It shows up super small and doesn't really have a scale factor that fits the bone i'm matching it with.

Thanks for sharing!

Bravo!
Thank you for this model.
It might be time to recreate parts of the whole body in order to have an open source library. Since Zygote body is not open source and that 3Dbody parts proposes only brain parts; this job is still to be done.

I like it! Are we supposed to print it vertical as shown in the picture?

Hi SundayDriver,
I also wonder this answer. Have you printed any foot as vetical position? Thanks.

Dear DrGlassDPM,
Thank you for sharing a good quality model. i would like to ask two main things.

  1. How this model (ankle bone geometry only) reconstructed? from what kind of subject (information: age weight etc...). is there any detailed description? what kind of medical image used?
  2. what kind of purpose can we use this ankle geometry?. is there any restriction? how about to use this as a academic purpose?

looking forward your reply.

Best. Miigaa

Do you have any information regarding how this model was developed? Is it based off medical images?

This was developed from a variety of means. The early versions were from medical images, illustrations, xrays. Recent working versions are being refined by 3d scans of cadaver bones as well as Computed Tomography.

How large does this print? New to 3D printing so full of silly questions =)

The detail is such, that it could be scaled up to 2x normal human size and still look decent.

Sweet! Thank you for the reply. I don't suppose you know of anyone with models of arthritic feet? Looking to develop some public engagement props.

Off the top of my head, no. However, I have included the original LWO file for lightwave. They could be modified to look more arthritic

Very nice Dr. Glass. I appreciate you taking the time to construct this.

no problem at all. I was just telling my colleague at the office here how fascinating it is to see that a model, which was assimilated from 3D scans and photo stitching of real cadavers (remeshed of course) has now been printed off and duplicated around the country/world.

Blows my mind when I think about it

Hello, this is brilliant work. I just wondered if you'd considered doing a Circle of Willis / Cranial Vasculature .stl?
I have an MRI dataset but am struggling to segment it - any advice welcome!

MRI Data is a little more difficult to reconstruct to STL that CT data of bones. It will still serve as a good reference though, if you want to re-topology it. I would suggest isolating the Circle of Willis and trying to export that as a starting point. I end up using Lightwave to Re-topology it or Meshlab. Are you familiar with these techniques?

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 for that.

If suggest you contact my friends over at http://carrythewhat.comcarrythewhat.com they are very reasonable and have quality machine output. Give them a go!

Please make more skeleton parts!  I LOVE my foot--beautiful print.

I've got some updated bone geometry for these parts, as well as the rest of the leg and knee.  After some refinements  I'll upload the 2.0 version!

Glad you like it,
Nick

please use binary STLs.

You could use repsnapper to batch convert them.

I uploaded the OBJ format files in the OBJ.zip package.

Very impressive Dr. (Nicholas).

Thanks Brian!
