The Rook - Chessboard

The Rook

The tower and the playing field have recesses for magnets. This makes it easy to wrap the playing field around the tower. The tower has 3 levels to store the game pieces.

Necessary parts

Printed

• 8x Playing fields (16x half Playing fields + 32 Connector)
  • Corresponding Tiles
• 2x end piece (2x lower end piece and 2x upper + 4 Connector)
  • Corresponding coordinates and end pieces
• 4x End spigot
• 1x Ground
• 1x Groundfloor
• 1x Second Floor
• 1x Third Floor
• 1x Tower top
• 1x Tower top floor

Other

• 1x M4 threaded rod 325mm
• 2x M4 Washer
• 2x M4 nut
• 64x 15mm x 2mm magnet
• 8x 10mm x 2mm magnet
• Rubber bands or similar
• Super glue

Filament Used in my Version

• R3D Silk Copper
• Buddy3D PLA White
• Prusa PLA Jet Black
• Buddy3D PLA Stone Marble

Don't forget the Magnets

It is essential to print the magnets in the recesses so that the playing field and the tower can connect.

For example, the “Groundfloor” needs a Stop at layer 99 [insert eight 15mm x 2mm Magnets]

and at layer 180 [insert two 10mm x 2mm Magnets]

Magnets per part and layer

Disclaimer, layer heights for 0.2mm layer heights and alignment as downloaded.

• Groundfloor
  • Layer 99, insert eight 15mm x 2mm Magnets.
  • Layer 180, insert two 10mm x 2mm Magnets.
• Second Floor
  • Layer 99, insert eight 15mm x 2mm Magnets.
• Third Floor
  • Layer 99, insert eight 15mm x 2mm Magnets.
  • Layer 450, insert two 10mm x 2mm Magnets.
• Tower top
  • Layer 99, insert eight 15mm x 2mm Magnets.
• Half Playing field
  • Layer 13, insert two 15mm x 2mm Magnets.
• Playing field
  • Layer 13, insert four 15mm x 2mm Magnets.
• Lower End piece
  • Layer 65, insert one 10mm x 2mm Magnet.
• Upper End piece
  • Layer 65, insert one 10mm x 2mm Magnet.
• End piece
  • Layer 65, insert two 10mm x 2mm Magnet.

It is important that the magnets of the tower parts have the same orientation and that the playing fields have the orientation to be attracted. Otherwise the tower will repel the playing field.

Printed Parts

I have designed several versions to provide options for larger printers and printers with MMU functions.

For example

• MMU-capable printers could use the parts with blind coordinates and complete the labeling in the slicer.
• Larger printers can print the complete playing fields. This means that they do not have to be connected like the half playing fields.
• MMU printers can color the playing fields with tiles. This means that the tiles do not have to be printed and glued in separately.

Assembly of the playing field

Connecting the playing field parts.

I have found it easiest to start with a thread through the end spigot. Then the elastic band can be pulled through with the thread as an aid. (It's best to use long rubber bands, I used three because I didn't have any others to hand.)

The thread technique can be repeated on the other side.

The Prototype

The first version of the Rook was made in Tinkercad and printed on my ender 3v2. With more experience with a professional CAD programm and the new Prusa printer, i wanted to revisit the Project and now i am at a point i can publish it.
