I machined one side which has a arbor machined into it for the reel to sit on.
Then on the other side its just a cap strip using 3mm machine screws. The main
hole for carabineer is done using 1/2 drill and then slotted on center with an
end mill to allow use with a delta carabineer as well. Then machined to allow
sitting at an angle on the carabineer. This one is hand made and I don't have
the time to hand make them. I could have them CNC machined but I doubt guys will
pay for it.
