Progress on the D-O Parts mixture assembly

Having parts in 3d from several downloading times from david's thingiverse page,  i am totally confused now in assembling the parts.
Some fit perfect, some not.
Some.needed to be printed again, some are still missing. Unfortunately david's page is covered now, so now you have to donate money to him.
Pretty fair, but those first version parts were for free.
Now i have to see, what i can do...
My son will help me with the CAD work on the parts hopefully.

Here is an actual picture of the Droid:
