I first printed this with 10% infill, which made it osteopenic and it broke during the build. No worries, I changed that to a denser infill. The design is wonderful. I am able to pair this with my commercial forearm to show my patients how the ulna interacts with the humerus. It looks weird in any color except white. I have an ultimaker 2 extended, and reduced the size to 80%. Thanks for the design!

Thanks for printing my model. ... I like the 'osteopenic' joke. Enjoy.

Well, first, thanks for printing my bone. ... as to having higher res and "On mine you can see the triangles of the mesh in the print." you have me at a bit of a loss (since I don't know the type of printer or material you are working with). ... If you are extruding at 200 microns (0.2mm) that is already 'high res' in ABS, there should no 'visible triangles' ? I routinely print this model for our Anatomy people at 400 microns and in Solid White they always look real nice. ... Three items come to mind - File corruption download, the addition of "BRIM" , why brim? and "no support used." ... Try standing each half upright on the bed - remove BRIM - and generate rectilinear support w 2.5mm spacing at 400 micron.

Printing this as an example of 3D printing for Archaeology students at Uni of Sheffield. Will upload some pictures when its done. So far printed the lower half @ 200 microns with no support at all and a brim of 30 outlines. Came out very clean! Any chance of a high resolution version? On mine you can see the triangles of the mesh in the print
