Models exported to 3d print utilities (ie PreForm) currently have less-than-helpful names in the print utility (random numbers and letters). This is the case whether you export from the built-in 3d print command or using the python / C++ API. It would be very nice to be able to specify the name the model should have in the print utility using the API.
For example, sometimes I want to print off several versions of a piece at a time in order to test a range of model parameters. If I include the parameter values in each version's name (which the print utility automatically prints on the base of each model), then it's easy to match the printed models with their respective parameters. I actually have a script that does this for me, but right now I have to export the .stl files to some directory then open them in the print utility manually, rather than sending them to the utility right from the API.
