I couldn't see my garmin if I mounted it on the stem while riding my tri bike. So, I wanted to move it up closer to where my eyes could easily see the device. I devised a way of mounting the garmin to the water bottle. It's a profile design water bottle and fits very snuggly and doesn't shake. My bottle is slightly dented, so if someone wants to use this design I can very easily change the dimensions of full length to accommodate your bottle, just let me know.

The garmin mount is integrated into the design and isn't replaceable. I printed it in PLA as I don't expect it to see extreme heat. If need be I think you could print in PETG as well. The flexibility helps it bend around the water bottle. It seems extremely sturdy to me.
