This is a spinning pool filter stand. When you spray the filter to wash it the force of the water spins the filter helping to get it clean Inspired by Cyclone Filter Cleaner… but this version does not cost $300.00!
It uses printed parts, ¾ inch dowel rod and a sealed bearing. (Amazon Flanged Ball Bearings ID 3/4" x OD 1-3/8")

Print the pieces with build plate supports and orient the bottom bracket and top bracket with the flat side down. Note pick either version of the feet and print 4 of them. Version 2 of the feet has just a small design change, but both work.
Fits my Pentair filter with 6 inch opening.
Happy washing.
Updated: added a 3 inch opening version.
Updated: added picture of how the bottom and bottom bracket are positioned relative to one another.
