As @Chris Celek mentioned, I'm pretty confident the slots are intended to be used for things like parking cards and such, I've seen them in many other VWs as well. Are you sure they are actually open all the way through to the underside of the center console?
Really excellent design work Geo. I'm sure many without a 3D printing capability would love to know if you ever plan to make a few and sell them (me? )
In the meantime you've now got me thinking about double-stick taping my sunglass case in that location.
One step ahead of ya, pal. 😎 That’s an old sunglass case that had the flap break off, perfect for this application since the RWD ID.4 doesn’t accelerate fast enough to send them flying. 🤣
