A hook and and a "spreader" to help you dry your 3l CamelBak bladder.
This is a remix of theRatchets excellent design for 1.5l bladders - thanks for sharing the .f3d. I made hook and spreader and bit larger so that it fits better for my 3l bladder. Also both are a bit thicker since I it broke a couple of times when removing it from the PEI.
I used Spectrum PETG in yellow which (accidentally appears to fit the former CamelBak colors), but anything else should do.
The author remixed this model.
