Building a low-volume CIP solution for the Grainfather GF30 Conical Fermenter

After my brewday I us a low-volume CIP device from Kegland to squirt water mixed with cleaning compound inside the kettle, which gets rid of any residual hop or grain gunge and this works well, but I did not have a way to use that CIP device in my fermenter when my beer was finished.

I had this idea to stand the fermenter ontop of the mash kettle and use the kettle to pump the cleaning fluid up to the fermenter and it would wash the inside of the fermenter then fall back down into the mash kettle and the process repeats... to do this I needed a couple of things; 1. An adaptor to hold the CIP device inside the fermenter 2. A solid base that could clip onto the top of the kettle rim, which the fermenter logs could clip/slot into ... I decided that I needed a doughnut !

	Using a palm-router attached to a circle-cutting jig, I cut a doughnut shape from some 12mm plywood I had lying around.
	It came out pretty well.
	I then 3d printed 4 clips fr the bottom of the base, to secure the doughnut platform to the brew kettle rim.
	I used ABS-like resin for all prints, which will be plenty strong enough.
	Then I had to check that I got the clip alignment circle to match the rim circumference ...
	... all good, it fits perfectly.
	I then turned my attention to the 4 feet that I would need for the top surface of the doughnut, in which the Fermenter woud stand. I cranked up Fusion 360 and after a few dud designs, settled on what I thought woud work.
	3.5 hours later I was pleased with how it turned-uot ... 3 more to go.
	With all four attached it was time test the fit.
