Those inserts look like they should be laser-cuttable. It is more work on your part, because you have to then assemble the 3D structure from 2D pieces, but laser cutting would be substantially quicker and cheaper than 3D-printing. My counter setup is entirely laser-cut (similar idea, but designed to fit in the MMP boxes rather than in RAACOs), and I'm pretty happy with it.
