My FIL complained to me that his peloton had wimpy little holders for itty bitty water bottles, which obviously wasn't suitable for his big chungus water bottle for his 12 hour bike rides. So I modeled this up so he can stay hydrated while he plays with his expensive Wii Fit. It isn't perfect, I'm a bit new to CAD, but it bolts right up, and has been reliable so far.
UPDATE I found that the vertical print orientation wasn't working for me, the bottom broke off multiple times. I made new versions that print on their back, and are much more durable in my testing. I printed without supports, and some of the overhands look a bit rough, so add supports if you care about that.
Fits a large Hydroflask and large LTT waterbottle.
