Tamiya Robot Platform Upper v1

I'm working on building a robot using a few tamiya track parts kits. I hope to have a series of 3D print parts to assist in the construction of it. This is an upper piece designed to mount a 12mm X 24mm servo and cover up a battery pack and wires. It's designed to mate specifically with a Tamiya track kit's wooden block, but you can screw it to whatever using self tapping screws.

I'm hoping to evolve this part as I get more parts in. Right now it's designed to hold a servo to mount a sonar
