About this 3D model

Name: R 3a Outer surface: Ø65 spherical face with locking groove Inner surface: Ø45 spherical face with locking groove Length=15mm Radial and diagonal Ø3 locking holes - A full ring consists of 2 ½-Rings, put together and fixed with a piece of Ø2.85mm filament It is used as a wheel or as a 'base' for Ø85 Rings, that will be able to rotate in a spherical way around the Ø65 Ring. It can be locked in a way that allow the Ø85 Ring to rotate around the center axis. Finally the Rings can be fixed together so they will act as one Ring. - This module is part of the 'He-Ideas' mechanical building set See more on my web-page https://he-ideas.weebly.com
