Gardena compatible adapter for 8mm hose

This adapter can be used to connect a number of 8mm (inner diameter) irrigation hoses (e.g. those used in the Blumat irrigation system) to a normal garden hose. 

Disclaimer: Only to be used with low pressure systems!

The original FreeCAD file is included to allow easy modifications. 

The provided variants with one to five outlets can be printed without supports but use of a broad brim should be considered to improve bed adhesion.

The model shown in the photo was printed in Prusament PC-Blend Orange at 0.15mm layer height, 3 perimeters and 6 top/bottom layers. Sparse infill is sufficient (10-15 %).

The model requires a Gardena o-ring (available in packages of 10 or so as replacement parts). 

If you make one, please share and comment. Suggestions for improvements and remixes are welcome. 

Note: The variant with one outlet is there for completeness' sake, this should probably be designed to have the outlet centered.

Edit 2024-07-29: Added a FreeCAD-File that should work with FreeCAD-v0.22.0dev
