Blender has a built in option to batch export STL files but it replaces spaces, "(", "[" with underscores which I don't want.
For example:
What the object is named: Sprgr L4.5 Patr (DoppZ S-60 Fl) 1-1 scale - [ 88mm KwK 36 ]
What it actually exports as: Sprgr_L4_5_Patr__DoppZ_S-60_Fl__1-1_scale_-___88mm_KwK_36__
Does anyone have a working plugin for 2.8x that doesn't screw with the name? Or perhaps some simple way to avoid this problem? I don't want to be renaming each file manually. Especially when I have over 10 000 files to export.
I wouldn't mind trying to hack together a plugin but my understanding of python is basically non-existent. And taking an existing obj batch exporter plugin and replacing "obj" with "stl" is obviously not going to work.
This is the obj batch exporter that I'm using and works great:
