Was thinking about Metru shoulders again and wondered about a construction like pic related, which would give better articulation while also preserving the ability to hold a standard Metru forearm in the correct orientation. But it relies on a piece I'm not sure exists, being this 90-degree bit with two axle holes. I know there's one where the connections are pins, but obviously that wouldn't be stable.
So does that piece exist? Or are there similar alternatives with axles at 90 degrees to each other?
One problem is that the upper limb would gain length, but it'd at least be one way to incorporate the Metru shoulder armour in a simple build without too much extra Technic mess.
