Exported .STL doesn't maintain size when viewed in Mattercontroller

I don't know if this is a Oneshape issue or Mattercontroller issue, but when I open a an exported .stl file in Mattercontroller the size is drastically shrunk. The resulting object is like 1% of the original size. If I open the .stl in Tinkercad it appears to be the right size. I can then re-export it, so it will work in Mattercontroller. It also appears that online-3d print calculators think the object is super-small. This makes me thing the issue is on Oneshapes side.

Could it be off by a factor of 25.4? If so, that suggests a unit conversion issue. For example if the object was designed with units of inches, Mattercontroller may have imported the STL file assuming units of mm. A one inch cube in Onshape would look to Mattercontroller like a 1 mm cube. That sort of unit conversion problem is common with STL files, I think.
It looks like Mattercontrol is a 3D print slicer - if that has a scaling feature try using 25.4 as the scale factor and see if your object size looks more logical.5
