The hose on my Bissell SpotClean Pro broke right at the wand fitting. The original fitting was glued with some kind of epoxy and was unusable. Remade the connector to the best of my abilities. Make sure to reuse the original oring. I printed with adaptive layers set so the threads would print well. I wouldn't recommend printing with anything under 0.2 layer lines. If you want a permanent bond to the hose I would use some kind of glue on the threads when screwing the connector onto the hose. Also if you use very hot water in your unit I would use petg or a similar high temp material, else pla should work fine for most applications.
The author remixed this model.
Used the thread pattern scaled to fit a 25mm hose as the hose side, and made the rest of the model to fit the bissell wand.
