Pi bar water bottle cage?

Hey guys, I was trying to find a water bottle cage to attach to the Coker Pi Bar. Are there any simple solutions for this without drilling holes? I see lots of people are using camelbaks, but I don’t really feel like spending much money.
Any suggestions? Thanks.

Try using jubilee clips, or heavy duty cable ties. Fix the cage onto one side of the bar and twist it so that the bottle sits between the bars.

Post a photo when you manage to get it sorted.
