Hey everyone,
With the investment of a 3D printer, my brother and I have printed original sized battery box tops for the Urban Express Deluxe model! Take a look at the attached photo! With this top we've made, I have dremelled the sharp support edges down and will sand them with fine grit sandpaper for an original look (not sanded yet in photo). This design is an original design from scratch created using the height measurements of a standard NU50 battery box top and the measurements of the bottom tray of a Deluxe NU50M battery box so that it fits right on the original Deluxe battery tray. Keep an eye out for an eBay listing within the next few weeks.
Thanks!
