About this model

Water butt bung to plug up an old 1 inch / 25mm pipe connector hole (I couldn't find one to buy so made this one). Requires 2 soft rubber washers and may benefit from a light smear of sealant on the washer surfaces and threads. Threads may require a little a little light clean up after printing, but some roughness is good as it helps the thread lock in place once secured. Secured using an Allen key and spanner from inside the tank. Uses 3rd party libraries for the threads and Allen key socket hexagon: Fully parametric design in OpenSCAD so easy to customise.
