I'm the kind of person who hates wasted space and I didn't like that my Aerosport center console (without the throttle quadrant) had unused space. I designed and 3D-printed a cupholder that fits in here and fits most containers very well. I'm happy to share the STL if anybody else is interested.
The carbon fiber portion is the Aerosport center console (without throttle quadrants). I designed and printed the cupholder and flange, then cut a hole and attached with epoxy.
