*Jan 3 2025: If you had downloaded the new 6x3 profile below, be aware it was uploaded with some errors and those pieces probably wouldn't have fit inside the slots in the storage box. I have replaced the print profile below with the pieces that do fit in the box.

NOTE: I have removed the pieces themselves from my print profile, and instead moved them as a new print profile under the original model. Use the one titled 6x3magnets: https://makerworld.com/models/425953 . 

For this Harry Potter Wizard Chess set, I designed a storage box to contain all of the pieces. The storage box is split in half, one color per half, and the two halves connect together with 6x3mm magnets.

My print profile has negative parts just under the surface of each piece's slot, so you'll need to verify that there's a Pause command inserted at the correct layer; while the printer is paused, you can put in the 6x3mm magnets (it's a tight fit, but they go in with a little encouragement). If you're careful with the polarity of the magnets, the embedded magnet in the storage box should roughly line up with the magnets you put in the bottom of the pieces (Note, the pieces themselves don't have embedded magnets, just slots for you to glue them in afterwards).

You'll want to turn on Arachne Wall Generator.

The pawns are two rows of four, and to make sure the bottom of the second row printed well, i removed those ‘shelves’ and they get printed separately. They can be glued in afterwards. Note, their widths are not equal, so each of the shelves corresponds to a particular slot. In my print profile, i move one of the shelves to a separate plate so you can test the tolerance of the magnet slot.

The lid has some embedded text ("Harry Potter Wizard Chess") in it, so with an AMS you can use the fill tool and paint the letters a different color. My profile has this done already. Note: when i printed my lid, i used one of those holographic smooth build plates to great effect. However, I did experience a little bit of lifting at the four corners. The lid still printed well, but just something to be aware of.

There are little bulges at the corners that help keep the boxes attached to the lid. When I first put the lid on, I had trouble getting it off. Once I did, a little bit of sanding/filing of those bulges made it come on/off easier.

I used Octogram Spiral for top and bottom surface patterns. I recommend avoiding gyroid infill; when printing the storage boxes, I had my infill set too low, and some of the bridges didn't quite work. Set your infill high enough and you won't have this issue. 

I printed the chess pieces at 0.12mm layer height, and the lid/boxes at 0.2mm.

Due to the size, this will not fit on an A1 mini, as the lid and storage box barely fit on the 256x256 P1S build plate.

I used Silver and Gold Leaf Rub ‘N Buff for the two colors of the pieces; I printed both sets in black, and then differentiated them with the Rub N’ Buff. For the storage box, I used ERYONE Glitter PLA, Burnt Titanium Blue color (https://a.co/d/eRxD07E). The lid i just used silk silver for the words, silk black pla for the body, gold silk pla for the accent stripes, and the same Eryone glitter for the bottom layer surrounding the text.
