This is a replacement engine grill for the Heng Long 1/16th scale RC tank.

Supports are needed for the 3 mounting pins only.

However, I find it best to "hover" the whole part off the raft, and print the entire object on a bed of rafts. Otherwise the part sticks to the raft and breaks when you try to separate it from the raft.

I just replaced the .stl file with an updated version that recesses the surface of the grill slightly so there is a separation between the border and the screen. I didn't update the pictures but the 3D view will show the detail.
