Summary

Lowered down the water mount angle so a cage could fit on top and gave a bit more width support at the bottom. Changed the mounting holes to the bike, they were a few mm off for my Speedmax.

Add a layer of carbon fibre on each side to give the pla some more strength.

Thanks to PSomeone for sharing the original file, I love your work.

Removed double hole near the top in the latest version 3. That is where the mount broke after 6 months of riding.

Now using a slightly shorter version (bottle is closer to frame) which is stronger and just using 100% infill with PLA+. It is very strong and I have been using for a number of months on training rides and races. I have also been printing it side down.
