FWIW, I would probably break this into three STLs using a DIFFERENCE method, stretch the outer ones using a SCALE method, then use a UNION to put them back together. If you only need a few millimeters, you can probably just stretch/scale the entire model by the required amount in all directions (to maintain angles/proportions) and the screw holes will still be close enough to the correct size to work fine. Press “s” to scale. It looks as follows. The challenge for a designer is to find the perfect trade-off between having a well-detailed, non-pixelated model and a file that is small enough to be easily shared and uploaded. Not all models are made with solid modellers. Again, this is what happened: The stl file just defines the size of the adapter as 35,98 x 35,98 x 9 “units”. Now, if you have a 1cm high model in blender it will also be 1cm high in Slicer… in 123d I would fill in the hole with the merge union (with a cylinder object), scale it, and either keep it unfilled and drill it, or do a subtraction union on where you want the holes. Then you can adjust the value and export a new STL. Cura is the software that allows us to prep the .stl files for our 3D printer (Ultimaker2).

It will immediately tell you by how much percent your file size (and polygon count) has been reduced. This means that the print time is determined by the Z height of print job and is independent of the X-Y size. This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. It's worth mentioning that this works for OP's case of an empty vector, but if your vector already has elements, this will not resize the existing ones, so you will only get the exact desired dimensions if your existing elements are already of the desired dimensions (for instance, this will not properly resize an existing 2x2x2 vector up or a 10x10x10 down, but will work for a 1x5x10).
