MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Thanks for noticing. It takes a village to find the gremlins; I am sure there may be something I have missed.
Actually the file is an OpenSCAD file not a .stl file. 2K is the size. If you click the "Open in Customizer" button on the Thingiverse page, you will be able to enter the parameters that work for you and then create a file to send to your printer software. (Or, you can download the OpenSCAD file itself and then edit it with OpenSCAD to modify it for other purposes. OpenSCAD has something of a learning curve, but it is free and it does work.)
