Mostly the same as SPRINKLER base model, but with the BSP 0.75 threads of the inlet port replaced so that they extend to the outer part of the inlet port.
The .f3d file is included in case anyone wants to see how the threads were replaced.
The SPRINKLER_slicer_file.3mf was saved in PrusaSlicer 2.5 alpha3 (yay Arachne). YMMV with the inlet thread supports.
See remix for US garden hose adapter that allows using a US garden hose (0.75 11.5NH maybe - seems to work) with this BSP 0.75 inlet port.
The author remixed this model.
