I updated the two base parts to the correct versions with holes for the feet pins. See "WMammoth_Base1_v3.stl" and "WMammoth_Base2_v3.stl".
I updated the four "feet" models to the correct v3 version. The previous ones were missing the connector pins to snap into the base parts. I also updated the pelvis-spine-skull pins model to be a smaller file size, but you will need to print three of them, hence the "x3" in the file name..
The source file for this model is the 3D scan of a woolly mammoth skeleton from the Smithsonian Institution National Museum of Natural History site at: http://www.3d.si.edu
The scale of the .STL files is 1:10.
I separated the original model into printable pieces and added snap together features to make it easier to assemble. I also added a two-piece to make the assembled model stand properly and improve strength. The model in the pictures did not have snap features so gluing it together was difficult. I have not tested all of the snap fits, so please let me know of any issues if you build it.
The model in the photos was printed at 75% scale to fit the 205mm square bed of my printer. This makes the final scale of the model in the pictures 1:13. The height of the assembled model is approximately 350mm (13.8"), or at the 75% scale to fit most printers the height is approximately 260mm (10.3")..
