I can't imagine using this in the Netherlands with random rain. The tradeoffs are hard to accept, wondering how it looks and performs in various weather conditions, and if a physical buttoned shell is worth it...
Weather sealing is quite doable if you accept you need a boatload of glue and you coat your 3d printed case with proper car lacquer or at least a thick coat of acryl. Use reinforced filament, and at least something 70c+ resistant (so no ordinary PLA).
I've driven it plenty in the rain in NL (not this display, my own).
