Summary

This is used to keep the pool hose under water. I needed this as I added a swivel connector that sucks air when not submerged. This just clips over the hose.

Printed this in ABS with 4 walls and a 15% rectilinear filling to create big enough cavities for the BB's. I paused the print at 75% and added 4.5mm (0.177 cal) metal BB's to add weight. Works really well and keeps the hose submerged.
