STL files contain single precision coordinates and are generally not

In this case, your file "Holder_as_rendered.stl" is in my tool reported
as having 48 collapsed or zero area faces. This classification is
obviously subject to tolerances and interpretation.
A face is here 'collapsed' if one edge is shorter than the distance
tolerance (default=0.01) and has zero area if the computed area is less
than the area tolerance (default 1.0E-6). 48 of the faces in your file
failed one or both of these checks.
I uploaded a version of your file with those faces removed, you can get
it at (expires 2018-10-09 @ 18:00:06 GMT)
