VW Caddy Mk3 Cup holder insert

The two front cup holders in the VW Caddy Mk3 (specifically the 2010 to 2015 facelift variant) are too wide for some common 500ml drinks bottles, and there was a lack of anything fit for Free Culture on the various places to get 3D models, so I threw something together.

I've made two variants, one with holes for decreased material usage and increased coolness (subjective), and one without holes if you'd rather something easier to print.
I've successfully printed the version with holes using no supports, but your mileage may vary.
