I have a couple printers myself, but even without a printer I think it’s safe to assume we all have ShapeOKO’s or we wouldn’t be having this conversation. I don’t have a Sweepy, but looking at the design I think it would be simple enough to CNC two “donuts” from MDF (or ply, or whatever 1/2” or better thickness scrap you have laying around). One donut fits the Sweepy, the other donut fits your hose of choice. Step 2, glue the donuts together. I’m thinking 30 minutes from design, CNC, glue. Step 3 wait for glue to dry (I like 5 minute epoxy for such things). Step 4 assemble and start “Sweeping”. This MDF donut design obviously could be further refined.
