This is from a size 11.5 (not to scale) Adidas Ultra Boost 3.0 in Trace Khaki. Should be moderately easy to 3D print given you use some support for the lace aglets.

How I Designed This

3D scanning with Autodesk ReCap Photo

I took a bunch of picture of it from every angle, then used Autodesk's ReCap Photo to create the 3D file. It took a little cleanup work, and I sliced off the bottom to give a nice, flat printing surface.
