Wheels with groove and colored insert

This is a simple remix of parts "track_wheel_tension_V1", "track_wheel_V1" and "track_drive_wheel_54_V1" for the RC Tank published by Staind.

I wanted the wheels to look a little less bulky, so I included a spherical groove on both sides. And to add a little color, there is also an insert available for both wheels.

You don't safe filament with this, as you increase the solid area by taking away some volume which would have been printed with only a certain percentage of infill.
I printed it with 3 solid outer parameters and 3 solid layers top and bottom.
Infill is 15 %.
