Bellows cover

I'm using two of these bellows to cover the upper and lower exposed portions of the lead screw on a force meter I'm using: [this one](https://www.amazon.com/gp/product/B0BZRV2L2Z). I cut some MDF and it got dust all in the grease and I had to clean and regrease it GRRRR. So yeah, here we are.
I printed this using [TINMORRY TPU](https://www.amazon.com/dp/B0CHF626Y4). I like the filament pretty well so far and it's cheap so bonus. If you don't like the color you do you boo.

The inside diameter is 17.5mm and the screw holes are 4mm. I highly doubt that the mounting pattern I'm using will match what you need hence the step/f3d files. I added "Bellows Parts.stl" and .step that has only the two basic components needed to make your own length (multiples of 10mm). Just flip the base. The split components are in the f3d file along with the sketches.

Compressed length = design length - (number of pleats) * 6.5-7.0mm

The STEP and f3d files are the latest version (newer than my printed version)
