I spoke to Darren at Spoox yesterday and he's more than happy to have another look at these caps for us. He no longer has the template for the cap but I have a spare one that I will be sending him. Once he has the cap he can take the required dimensions, mock one up and then come back to us with a price. He did mention that 1 off's would be a little more expensive due to the set up times involved in machining which I fully understand, so if there are a few members who would like a nice shiney cap there would be more benefits around the cost of a sort of 'Group Buy'.
I'll get the cap off in the post on Monday and keep you updated. Anyone that's provisionally interested, add your name below.
