I need to buy a few collimation caps, but cannot find any good source.

 

AgenaAstro has one listed, but out of stock.

 

These are proving to be very challenging to find.

Not trying to be pithy but can't you just make one?

In the UK on ebay.  Weeks to get though.

If you have an old camera film container around, take some care and make a tiny hole in the middle of the base. A classic.

I know, right? Who has a film container that's days? Experiment, maybe a medicine container can be found to fit. Or an end cap.

I could make one, but I like the precision hole and the reflective material on the official ones.

I created one in Solidworks and printed it on our 3D printer. Heck, I might even sell these on ebay!
