Argh, bugger!
All is not lost. The cap will work, though it can be more tricky to get the secondary right with it.
I've done a couple of tricks with a couple of caps I've used over the years. The easiest is to paint a white ring around the hole that faces the secondary mirror. This makes identifying the cap and the hole a lot easier. Another is a ring of reflective tape around the same hole.
The good thing is that long Cheshire eyepieces are not expensive. I too got rid of mine when I thought a laser would cover it all. Didn't I learn that lesson...
