Brompton Front Block Bottle Holder

I have a Brompton, but what I didn't have was anywhere i could put a water bottle for those leisurely ridesI created a water bottle that mounts to the front luggage block of a Brompton (so can easily be removed and fitted when required. I wanted the design to be as lightweight as possible so id didn't just look like a black toilet roll tube on the front of the bike. The design itself uses the block cover by jimschanz (https://www.thingiverse.com/thing:132096) to which i have designed and mounted the bottle holder and its base to form a solid unit. The design also features a front and rear hook so that a band can be placed over the bottle to further secure it within the holder. the next revision will have a closed hook on the rear so that the band can be attached without fear of dropping it. I also have a cap that the band passes through that sits over the bottle lid that i will upload separately.It is designed to fit 600 ml Smart water bottles with room around the outside for easy remo
