This print requires eight 6x3mm magnets. The smaller version only needs four magnets. (The picture shows the prototype. I noticed that at this size more magnets are better)

You must have excellent bed adhesion for this print or it is guaranteed to fail. If you notice some warping afterwards, use a heat gun to flatten the cover. Even if you have great bed adhesion, bending might still occur so consider this an advanced print.

There are colour changes at 4.2mm and 34.2mm. Print 12 pins and 3 wheels in total.

If you have no interest in adding spell cards to your Tracker Book, you can also print a smaller version without that.

Edit: Fixed a layer bug with the letters in multicolour-printing as it caused some useless tool changes. Should be fine now.
