Wanted to make a tringle pastry cutter. Set system to cm, drew design, just a triangle with an offset, and saved it. Sent the stl to hubby for printing, only to find it has changed to mm! Checked my drawing and it tells me it is in cm…

Going to be making the tiniest croissants ever if I use this!🤣

I’ve never had this problem, but the scaling function in any slicer will fix this

That is what happened in the end but it was annoying that I had to do that.

Did you set the export units when you exportrd the stl file? STL files don’t contain any unit information, usually the slicers use mm when you load a file.

That must have been it I guess. I tend to design and hubby takes it to the printer…🙂
