About this 3D model

With the round base adapter ring, 25mm round bases can be easily converted to 28mm, 30mm, 32mm or 40mm. The round base adapters have a thin slot on one side and are simply bent around the base and fixed with superglue. The adapter ring holds even without glue, but might then fall off. This simple design also has the decisive advantage that magnets that have already been installed do not lose their effect because the base is not lifted by the adapter. Variant: 25mm to 28mm 25mm to 30mm 25mm to 32mm 25mm to 40mm Note Before usage, the base adapters must be separated at the predetermined breaking point (0.2 mm high bar in the slot) with a craft knife. If the base is designed and painted, the adapter ring may not fit snugly. Therefore the gap in the ring can be seen more clearly.
