My model in Sketchup is 180mm x 90mm x 3mm. However, MakePrintable tells me the model is too small and has dimensions 18mm x 9mm x 3mm. Why is it dividing by 10?
I don't use Sketcup, but if you're exporting STL files, they don't contain any units, which might cause scale confusions.
STL files doesn't include the measurement unit in it. So when we receive a file for example 10 mm x 10 mm x 10 mm, we receive it as 10 x 10 x10 then it will automatically be set as our default unit.
You can scale back your model to the original size by using the scale feature, which is on top left bar.
We will be adding an option that will let you change the default measurement unit. This will assist you with keeping the right scale (if you design your model in mm, we will receive the exported model as mm)
