Filename rules

[PSLLSP]

Please, standardize rules for filenames of STL files, I see two different patterns, like

1x_tesioner-body.stl and x1_motor-shaft-spacer.stl

I assume that 1x and x1 means that that part should be printed only once. Please, define policy 1x, 2x or x1, x2 and rename all files to comply with that policy... I think that 1x is better than x1. Then filenames should look like this:
1x_tesioner-body.stl and 1x_motor-shaft-spacer.stl (or even fix a typo, then 1x_tensioner-body.stl ;-)

Or prefer 'x1, than filenames should look like this: x1_tesioner-body.stl and x1_motor-shaft-spacer.stl
