About this 3D model

This was a really cool design but the original files were non-manifold (not watertight) which my slicer could not handle (tried to print them anyway and it was a disaster). So I took the original sketchup file and fixed it so that it's a solid object with no holes. Printed just fine after those adjustments. Sketchup and STL attached here. I just glued the magnets in with superglue one at a time, inserting one thumb between the previously glued-in magnet and the next one being placed in, to keep them from flipping out (which they will if you're not careful). One easter egg of this design is they way they can conveniently be stored on metal surfaces as shown in the photo.
