HydroSphere Cleaner - Interior Cleaning Nozzle

The HydroSphere Cleaner is a 3D printed cleaning nozzle that features a multi-hole pattern on a sphere, providing 180° coverage away from the hose and 360° coverage around the hose axis. It’s perfect for cleaning buckets or any interior spaces where your hand or a regular spray nozzle just can’t reach.

Design: This innovative nozzle is designed to fit onto your garden hose, transforming it into a unique cleaning tool. The spherical design ensures that water jets spray in all directions as you move the hose around, making it ideal for thoroughly cleaning the interiors of buckets, containers, or any hard-to-reach spaces. Simply insert the HydroSphere Cleaner into the opening, and let the water do the work!

Assembly:

• I strongly recommend using a rubber hose seal inside the part (shown as black little part in the photos), or a printable TPU one, included.  This will prevent leaks.  It will work without it, but you likely will get some leaks unless you use teflon tape to seal the male end of the hose connection.

Printing:

• Material: Printed here with durable ASA, this model can be as robust as it is functional. PLA/PETG can work too.
• Layer height: Prints well at 0.16 or 0.12 layer height in ASA. For good threads, thinner layers are recommended.  Particularly to get good holes at the top of the sphere a height modifier for layer height of 0.12 is recommended for this section if the rest of the model is 0.16 mm layer height. If you haven’t shrink-corrected your ASA printing profiles, you may need to enlarge the model to ~100.7%. Should fit just fine for PLA/PETG prints.
• Orientation: The only reasonable orientation here is sphere-up :).
• Supports:  Supports are somewhat optional, surprisingly.  Here are pictures of when I printed with/without supports.  Organic paint-on tree supports on the overhang flat work well here.
