Air massage valve for tub/shower hydromassage Revita

After encountering issues with two out of 14 air blow valves in my REVITA hot tub hydromassage system, I opted for 3D printing replacements since they were unavailable as spare parts. The valve consists of two parts - one containing a plastic ball and another featuring an oring on the edge. Both the oring and the ball were salvaged from the broken valves. To streamline the process, I designed the screwed components of the valve. For the prototype, PLA worked flawlessly, but when printing the final version in ABS, I had to use a raft. Consequently, I included an essential printing plate file for ABS prints. Post-printing, I smoothed the dome using fine abrasive paper. In case of an ABS-printed valve, I initially needed to remove the plate on the head to ensure proper adhesion of the first layer.
