Delrin was suggested to me by Darren as a potential material for Headlamp rings. It turned out to be unsuitable for that and more expensive than what I already use, but I think it would be ideal for the lever bush as it is self lubricating if I recall correctly.
I'm sure Nylon would be fine on a low stress part like that though.
You might even be able get one off the shelf based on the id.
Is the peg cf too? Or aluminium?
I'm just interested if you have a bleed hole in your mould press, for surplus resin and air to escape, or if you carefully weigh out just the right amount of resin?
I like it and I'm sure you will find a few more bitz and pieces to make now..
