Evenflo Pivot Wagon to Uppababy adapter

thingiverse

This allows you to use Uppababy Vista baby seat, Mesa car seat and bassinet with the wagon. You really need buy the Upper Adapters, which are available from Amazon or Uppababy. I just added a screw to the counterbored hole, as that gives you enough to grab onto. You could also loop a string or add something else there, but I wanted these as flat as possible when packing them away.
