Well looks like we’ve all witnessed our first failure. Glad you made it back safe from that - I bet that was a pucker factor 5 moment.

Aluminum ones are gone or I’d offer you a freebee - I am running a few out of carbon fiber with a small inlaid groove for a delrin insert so it too will be self lubricating ( even though range of motion on this thing shouldn’t really need large amounts of looob).

whenever I finish those up and if they function as intended I’ll happily send you one for the fee of a bit of feedback if you at all need one still.
