Most of them will edit the stl's as well.Take the time to learn one. Try this for yourself by printing multiples of the same object, as long as the Z height of the print job is the same, the job will take the same time! Very short answers cannot do this, so please. In many 3D modeling programs, you will be asked to define the maximum tolerance, precision or deviation of your STL export. This tolerance is defined as the maximum distance between the original shape and the STL mesh you are exporting. Then you can adjust the value and export a new STL. By far the easiest program to use is tinkercad and its free. Check out this simple guide to learn how to do it! Please get in touch with us. Thanks for your answer but we are looking for comprehensive answers that provide some explanation and context.
