This Core adds more weight to the 1kg Eryone Cardboard Spools in order to work better in AMS.
I constructed it to work with d=10 x 50mm Material.
You can glue in the pins, then they're exactly in the center of the Spool.
but that doesn't matter much.
the 7 compartements allow an even weight distribution no matter how much pins you put in.
I use 6 Steel Pins d=10 x 50mm which brings the core to about 240-250g of weight.
the core stabilizes the spool slightly when the spool gets emptier.
