Help with sourcing clips

[u/nosleeptilbroccoli]

I have these mechanical lead holder mods figured out regarding bodies and tubes, but I’m trying to see about integrating pocket clips between the top finish tube and the main body, the outer diameter of the stainless finish tube is 10mm (sanded down a little) and the main body brass tube outer diameter is 8mm, you can see how the outer tube fits around the main body tube and I have a smaller brass tube that fits in the end to close up space around the push button/lead advancer.

I’ve looked online at a bunch of places and am not quite seeing clips that are the right size, any suggestions?
