ICP Fix for 2521909

I went to print 2521909 and found that as wicked as it was, I couldn't figure it out.

My hatchetman skills to the rescue.

The original design needed magnets. How do they work? I don't know. So I made these plugs that fit into the magnet holes and aligns the parts so you can glue them together.
