UPDATE: Added suction line adapters for 6mm hose, 8mm hose & standard garden QR coupling (credit to Jackout for the garden hose coupling design used) Original part is an 18mm thread 1.5mm pitch (used on 12v diaphragm pump fittings)
Ok, so I didn't want to pay the nice people at karcher £15 for 2 bits of plastic and a piece of hose....especially when I already had some hose and a hose filter, so I made this little adapter up based on the original OEM part. You will need an O-ring for this part to work. I used a 2mm x-section, 15.5mm o/d (11.5mm i/d) but similar sizes will probably fit and work.
material: ABS
Layer height: 0.2mm
nozzle size: 0.4mm
supports: yes
print speed: 30mm/s
Infill: 100% (ensures airtight/watertight print)
To fit to the OC3:
Remove the plastic depresser from the water inlet. Using the "+"-hole on the bottom of the adapter, remove the filter. ensure o-ring is seated correctly on adapter and press firmly into the OC3, DO NOT TWIST! the OEM part is twist lock but mine is a simple push fit.
