Cup Holder Bebe Confort Rainbow or similar stroller. You can reuse the main holder part from the original model and use both strollers with the same main part. Use 4 25mm M4 Bolts and 4 nuts to attach the adapter to the stroller. Than place the Cup holding part in. The Cup holder is mounted behind the stroller so the door passing capabilities of the stroller are not affected.
No supports needed for adapter and back plate parts.
The author remixed this model.
Main part is without changes. Modified adapter to fit another stroller so the main part could be reused.
