Hello, here is the second version of my Halo Ring Shower Head.

The outer geometry is the same as before but the internal structure is completely new. This makes it easier and better to print and more hygienic. I also have two new optical variants to offer, some of which can be printed without AMS.

I don't have a head that fits on the A1M, but if the demand is high enough, I can make one. Let me know in the comments below.

If you still have design drafts, you can write me your ideas privately. Then I will see if it can be realized.

Features are:
- Easy connection to almost any generic G1/2” shower hose
- Integrated filter to keep coarse particles out of the system
- 58x1.5mm holes in a double helix spray pattern for even water distribution
- Comfortable and easy handling for every hand

Print settings/suggestions:
I recommend printing with a Smooth PEI Plate for the best results (see pictures). Make sure that your print plate is clean and your filament is dry. You should also make sure that your filament is compatible with each other if you are printing multicolor.

Material suggestions:
PLA is easier to print than PETG and delivers more consistent and satisfactory results. PLA can withstand temperatures up to 60°C, which is sufficient at a normal shower temperature of 38-42°C. However, PLA has some properties that make it unsuitable for this application (more under Hygienic Information).

PETG is the better choice when it comes to durability and hygienic conditions. It can withstand temperatures up to 80°C, but is more difficult to print. Make sure your material is dry before printing, because the holes and walls were often printed unclean therefore the spray pattern was distorted and water leaked in some places.
The enclosed print profile is adapted so that water can neither leak out of the part itself nor run out of the connection. If the connection does drip, make sure that the flange that sits on the sealing ring in the hose is smooth. If this is not the case, you can carefully rework it with some sandpaper.

Hygienic information:
PLA is a material that easily absorbs moisture, which can lead to degradation and deformation in humid environments. Its surfaces are slightly porous, allowing dirt and bacteria to accumulate and making it less hygienic in wet conditions. PLA also softens at around 60 °C, causing it to lose its shape in hot water. On the other hand, PETG is water-resistant and retains its mechanical properties even when exposed to moisture. It has smoother surfaces with fewer pores, making it more resistant to the accumulation of dirt and bacteria. PETG is also heat-resistant, withstanding temperatures of up to approximately 80 °C without deformation. These properties make PETG a more suitable option for applications in wet or hot environments where hygiene and shape retention are important.

Cleaning:
Vinegar solution: For limescale and bacterial buildup, a weak vinegar solution (1 part vinegar, 2 parts water) can be used for 10-15 minutes for PLA and 20-30 minutes for PETG. Rinse thoroughly as the vinegar may attack the material if left on longer.

Spaces: A soft toothbrush or interdental brush can be used to remove stubborn scale and other debris from the individual holes and filter after soaking in the vinegar solution.

If you have any questions, suggestions or design ideas please let me know ; )
