And here it is holding an actual object...water bottle in this case. Seems pretty secure and acceptably handy. My biggest issue in driving longer distances in the 911 is less about holding coffee and more about holding bottles of water that are reasonably reachable. This does the trick I think...
Back side took a lot of fiddling but not too hard. The VW holder assembly has a couple of tangs to locate it laterally and longitudinally, just made a couple of bent pieces of sheet metal with appropriate slots and such, holds on very well.
Note also I made a new centre plywood support as the 964 is different. Had to slot it for the holder.
All the ABS work was just heat gun, hand forming, built a little wooden form for the divots, nothing too dramatic. Just took time.
I think it is mocked up well enough to go on to the next task, there are a bunch of alignment issues that have ability to do once we are in final assembly. Right now it is good enough to say "done".
