It wouldn't take much to build one out of wood but the problem with wood is it absorbs liquids so one would want to do it with plastic. I have some solid surface counter top material that would work but that stuff is heavy. Maybe make it out of wood and use a shower pan PVC liner to keep the wood dry. PVC liner is $40 bucks at big box store. I have the wood. $55 for that separator is a bit much for an injected or vacuum formed piece of plastic.
i was going to post asking about the price. that is a bit steep. this may sound gross, but is it possible to find used composting heads for cheaper?
i would think, with sufficient study, you could make one. pretty much anything that can be bought can be made.
