Further progress on arm designs. I’m working on a poseable arm design that has maximum poseability without being too difficult to make. To this end I’m trying to avoid design which useĀ circular holes, something I always find fiddly. This design is looking promising. I’ve built it up a bit at a time so I need to re-lay all the parts and do a full re-build. It’ll be tidier next time šŸ™‚

Here’s a PhotoShopped version of the same arm twice, to give a better idea of what the green shoulder tube is.
