Pond pump reducing adapter
This time I needed to enlarge the ID of another of my pond pump's outflow ports from 12 mm to 25 mm to suit a larger hose. Change the diameters in the OpenSCAD to suit your own installation.
Printed on a Replicator 1 using 1.70 mm ABS at 100% infill (watertight ...) with 0.2 mm layer thickness and 120 mm/s feed rate (go Sailfish!). Use a raft and print with the larger diameter flush with the build plate. Mk II - lengthened larger diameter end and reduced no. of large barbs to 3.
