Maybe by changing sketchUp model, you can get a white background directly?

Good morning to all of you.
I'm trying to contact Mark Jason Grundman. I would like to present him with a version 2 of SPGear quite complete.
The new version offers the following services:
Bilingual (English, French), easily expandable for other languages.
Automatically adapts to the SketchUp type (mm or inch)
Draws, in addition to straight gears, helical, conical, helical conicals, chevron gears, hollow wheel gears and globic screws.
The new version performs calculations to correct deformations in the case of very steep propellers (screw cases)
The new version also proposes to draw the adapted satellite gears (calculated automatically) and then place them correctly on the leading gable.
The app filters the compatible settings for each requested case as much as possible.
The new version uses and generalizes mesh drawings (systematic use of add_faces_from_mesh methods)
The new version includes well on the setting of the boring, the size of the flap, the design or not of a rimmed/rim and the direction of rotation of the helical

Good morning to all of you.
Is SketchUp performing well to produce STL gear files?
