Tank, Shuttle Bay Doors, Front Body

Here are the body parts to finish up the tanks front end. The gear box and arms to open the doors is under "Tank servo door opener mechanism" in my things. All of this stuff goes with all of the other tank parts in my things to build a complete tank.
I spent hours sanding and fitting these to fit right, but it turned out really cool. Worth the effort. Here is a You Tube Video of the door working https://www.youtube.com/watch?v=vqUzjV5_Pv4&list=UUCjC4uorEyPqZ48rLtGJbHQ
The one door (287) is 2.87" long and fits in all 6 places. Drill the screw holes out accordingly. Will have more info in the instructions.
Front cowls are made to fit on a piece of Aluminum channel on front of tank. The suspension block fits in the channel also, and holds a standard size MG996 180 degree servo, for opening the shuttle bay doors with gear drive and arms. The loops on top of the suspension block are for the front track tensioners to swing on with arms and springs. The holes in the middle cowls are so I can get a hex key wrench in to adjust the track tension. Pictures of tensioners are in the "front Idler sprocket and hubs", in my things.
Had a hard time printing some of these, some will have extra support that can be broken away when finished printing. Some of them are just too tall and the support collapsed. The extra support helped hold up the regular support.
Will have a drill diagram shortly. Still working on Battery placement, they hit the doors standing straight up like I want them. So there will be some alternate doors with clearance, and battery mounts coming soon. Still have the rotating turret to do yet, so stay tuned.
