Remix of Irrigation Hose holder 20mm, I needed something to support our 19CM irrigation tubing from Bunnings so I scaled up the original model slightly with tinkercad and cut the hole 21.5cm 

I set to print with 3 walls and detect thin walls on, also apply an outer brim to avoid the pointy end lifting off the print bed.

Fits this irrigation piping perfectly: https://www.bunnings.com.au/holman-19mm-x-1m-poly-pipe_p3120555
