I am very excited about openbuilds and very frustrated that stock is low for most parts at the moment!! I noticed, buried one of the blog entries there are 120 degree corner brackets that could be used for delta 3d printers. This is huge! I have been designing around the fact that I can't find anything other than 90 or 45 degree brackets (I don't have a 3d printer, so cannot make something like this). When will these be available?
