Nút bịt cho ống 8mm

This plug is suitable for 8mm (inner diameter) plastic irrigation hoses (e.g. those used in the Blumat irrigation system) to seal the end of the line, still allowing for infrequent purges.

The original FreeCAD file is included to allow for easy modifications. 

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 without supports. Sparse infill is sufficient (10-15 %).

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