Hyper Drive Arm parts

The Hyper Drive Arm part files i got are from another R2 builder. He built the parts by scratch. What a work! so tiny bits and pieces...
The pdf´s he sent me had to be changed to dxf, stp and stl files. A friend of mine helped me with that. To see, if the parts will fit nicely and the function is ok, i intended to print them as 3d parts. here is a view of them on the creality slicer:

Here they are. Not a perfect print, but they are OK for a first assembly...

I am still waiting for the remaining parts, that are still on the printer...
