Secret Nut - Center Setting Block

I made a quick took to help set the center piece to a very cool 3D print.

Here is the acorn with a secret compartment :

When printing this I found the center was a little hard to slide the top two pieces together. Printing the outer ring at 100.5% size seems to help quite a bit for my Prusa printer. Sliding the two pieces together was still rather harsh on the thumbs and some times I would break off the hanger on the top. I whipped up this quick little tool that helps to set these pieces together very quickly!
