The file 'Ender 5 S1 X-rail Clip 3D Printer Model' is (stl) file type, size is 3.3KB.
A simple and easy way to fix things to the x-rails of your Creality Ender 5 S1 printer.
Might also work with other models, but not tested.
In one project I added a threaded insert on the back - it worked fine too.
