It was interesting to have the option to not actually care about placement here.  I either made 90g, or I didn't.  Here's what I did make.  It took me several hours to grasp the implications of the half access bonder/debonder pair.  I needed to make C shapes from several different starting objects, and built up a large catalogue of operations that would do it.  At this point I think the layout is fully capable of solving the puzzle, but I cannot find the sequence to do so.

If there is a more powerful layout, and I've just been spinning my wheels on this awkward one, then I'll learn it at the stream.  Making either bonder or debonder full access led to too many immediate fail conditions.  If somehow 90g was impossible, well played kazyan.  But I think probably a few people got it.
