Panzer VI with interior and functional transmission

Hello , I just fond my account number and password
This is a 1:16 scale panzer VI middle production I designed six months ago.
Now you can download solidworks file
The cooling fan unit is working
This model is very accurate and detailed , if you are a model maker, look no further
Remember those axle inside the transmission should be 45# steel
This model is designed for 3d print If you decide to make out hull by aluminum,it require modification.

This transmission is functional however there is a noise issue ( bad design on lock mechanism), I fixed that problem on a MBT but it won't fit in this model .
in the end I realize I was wrong about model design , what should be done is a model with more mechanical engineer and creative thinking like a autoloader instead of historical accurate.

PS ignore the idler wheel file
