This is a small accessory item for Playmobil #5542 CITY ACTION water bomber chopper I gave my son for Christmas today. This part should have been part of the kit. It allows the water bomber to be hung by the rope instead of directly off the belly of the chopper. It clips into the basket the same way the basket would clip to the belly of the chopper.
It printed no problem for me without raft or support. Print it standing up (rotate it before printing). Be sure to take your time so the model cools as you go up.
