This is a simple single page application to allow for STL adjustments based on how your 3d printer prints. The default values are
what my printer produces from a XYZ 20mm Calibration Cube, but
you can simply insert your own numbers.
Instructions
Print a calibration object
Enter what the measurment should be
Enter what it is
Upload the STL file
Export the corrected STL file
Warning
Like anything with 3D printing use this at your own risk. It's free software, but that does not mean that it's free of bugs. Check your exported STL files before printing. There is no warrenty or guarentee that it will work, or that the files will be right.
