Can those be cut to make shorter?

I would think so. It's polymer plastic or whatever, plastic.

Igus do have quite a good technical help service in my experience on the
few occasions I have put queries to them. They also supply 3D printing
filament in various of their product formulations so you may be able to
use your 3D printer to print what you want.

Do you know where their STL models are?

I see a small sample, but I need the linear bearings.

Thanks.
