Gel Flask Bike Mount

Glad this came up. I just started thinking about this after my new race kit doesn’t have back pockets. So now I’m kinda screwed.

I have a 3d printer and decent modeling skills. Wonder if I can make something? I was just going to make a 3-4 gel holder that’s flat to go onto the top tube. But maybe I can do a flask holder instead?

Let me know your thoughts

very Interested
