Inspired from https://www.prusaprinters.org/prints/73962-lathe-cross-slide-t-slot-covers I made my own for my HBM 250X550 Profi Norton Lathe. - Good idea to keep cleaning work easy:-)
The short ones have a different shape, because they have to go under the compound to close all gaps that no chips can fall into the slots.
The long ones just stick in the 10mm wide T-slozs of the crossslide and close them.
The author marked this model as their own original creation.
