Designed this bottle holder for a friend, with a squashed hexagon mesh for lightweight strength that doesn't require support material to print.

As Athens isn't the most cycling friendly city in the world we don’t have bikes, so apologies for no bike mounted photos, maybe one of you guys can upload one!

It is designed to fit standard bike bottles up to 70mm in diameter. This should be the standard for most use cases but if you use a slightly bigger/smaller bottle you can scale it up/down a bit in your slicer (around 3% either way).

The mounting holes are standard for most bikes and use 2x M5 clearance holes spaced 63.5mm apart with some allowance in the tolerances for scaling the design as mentioned above (see slightly oversized oval holes in images).

We printed this design with Silver PLA [Real Filament].

To print this design we used an Ultimaker 2+ 3D printer and the print in the photos is printed with a 0.6 mm nozzle [you can also use 0.25mm, 0.4mm +0.8mm].
