I originally made this cup holder for my 914; then made one for the Boxster. It's made from two PVC plubling parts purchased at Home Depot. I took my faorite cup to the store and test fitted seeral fitting to get it right. The bottom fitting is pretty weighty and keeps the holder stable; the upper piece supports the cup. Some sanding to the inside may be needed for the right fit. I used Window/Door caulking to fuse the two pieces together and used the peel-off felt for a liner and base covering.
The cup holder sits on the passenger side floor by the seat adjuster. I don't hae to take my eyes off the road to reach the cup
A fun project..
