This handy unit both gives you a place to hang your gear bag, and also keeps your water bottle handy for hydration. The photo shows a version emblazoned with my local club's initials (Bellingham Pickleball Club), but the posted STL file is plain.

To assemble, just slide the band piece into place over the main body and glue in place (front and back) with a little superglue.

My original version tended to twist on some fences. Here I've added some ribs inside the fence hook to keep it stable. I also increased the size of the bag hook to accommodate larger handles.
