We like to keep our hydration pack bladders dry and open after every bike ride.

Drain the bladder, hang it on the wall, and keep it clean for your very next adventure.

Printing is easy. You need one of of each part . Everything can be printed without supports except the base plate which requires supports under the bridge when printed vertically.

Once printed, screw the screw plate to the wall, I used drywall anchors. Then slide on the base plate and screw on the poles.
