Rotating joint - concept

cults3d

I was really fascinated by this type of joint when I found it on cults3d: https://cults3d.com/en/3d-model/various/joint-koenig-impression-3d I just love the movement and the way it can transfer rotational movement in a given angle. To fully understand it I decided to make my own version of the joint My version of this joint is of course not fully 3d-printed, however I was able to make it more compact and smoother by using the metal pins. I'm pretty satisfied with how this turned out and think it has a lot of potential for something like a robot arm, but I'm not quite sure exactly how. If you want to make one of your own, here is the additional hardware: 1.5mm OD Pins: https://www.aliexpress.com/item/32915349219.html?spm=a2g0s.9042311.0.0.4a8a4c4dJPLrde 2.0mm OD Pins: https://www.aliexpress.com/item/32916012981.html?spm=a2g0o.detail.1000060.1.e6dd3e83PvK1pS&gps-id=pcDetailBottomMoreThisSeller&scm=1007.13339.146401.0&scm_id=1007.13339.146401.0&scm-url=1007.13339.146401.0&pvid=16351f4b-6743-4421-bec8-1c3a81075836&_t=gps-id:pcDetailBottomMoreThisSeller,scm-url:1007.13339.146401.0,pvid:16351f4b-6743-4421-bec8-1c3a81075836,tpp_buckets:668%230%23131923%2320_668%23808%233772%23946_668%23888%233325%239_668%232846%238111%23409_668%232717%237564%23651 M2 Scews: https://www.aliexpress.com/item/32810872544.html?spm=a2g0s.9042311.0.0.3d2e4c4dIpyhiK
