I don't like the various water hose attachments as they drastically reduce the cross-sectional area of the hose and cut the water flow.
so I made a friction-fit nozzle that slips over the hose from the outside In hopes that this design has fewer losses.
This design is intended to be used on a normal hose without any attachments

You can create a nozzle that imitates the squishing of the hose as usually done by fingers or make a firehose-like nozzle with this parametric file; everything is customizable.
Measure your hose dimensions and enter them in the f360 file.
Hose other diameter = Hose_Diameter
Hose wall thickness = Hose_Wall
To change the nozzle Slot size, change SlotW & SlotX values.
*(Should be SlotX > SlotW)
The included STL dimensions are for hose size 22.5mm with a 2.5mm Hose_wall. which is ¾"?
The nozzle dimensions are 80mm by 1.25mm.
I will add another sizes if you ask.
