## Circuit Playground Chess
Get ready to play with the Adafruit Chess set! It’s entirely 3D printed and features players from Circuit Playground.
In this project we’re using metal filament to 3D print the chess pieces. This filament contains actual metal particles. In this guide we’ll take a look at how to get this shimmer and shine so it doesn't even look 3D printed.
## Modular Chess Board
The chess board is a modular design that can be printed in regular PLA. The board pieces use puzzle like connectors that snap fit together. Assembly is like a puzzle game that doesn’t take too long. Simply snap them together.
## Prerequisite Guide
Check out these guide below for more details on using metal filament and polishing techniques.
- [Polishing Techniques with copper/bronzeFill](../../../../copperfill-filament)
## Parts and Materials
You'll need access to a 3D printer and filament (optional metal). For processing, we recommend using a rotary tumbler.
- 3D Printer
- copperFill
- bronzeFill
- Rotary Tumbler
- Brass screws
- Steel screws
- Flush snips
- Breathing Mask

## Metal Filament
In this project we used copperFill and bronzeFill filament from ColorFabb. It's a special blend of PLA with actual metal particles that's 3x times heavier than regular PLA!
Extruder Types
Works with most direct drive and bowden systems.
Operating extruder temperatures
210-230C
Build Platform
Use Blue Painters Tape
Heated bed use 60C
## Slice Setting
20% Infill
.15mm layer height
30mm/s Print Speed
2 Shells
230C Extruder
4 Bottom / 8 Top Layers
No Retraction

## Characters
The characters are separated into pieces. The parts are optimized to print with no support material. The parts can be printed in PLA or metal filament. To prepare the parts for slicing, we oriented the parts to be in the center of the printers build plate.
## Chess Board
The chess board is a modular design that can be printed in regular PLA. Pieces that make up the board are separated into 3 different parts. You can choose any two colors as your alternating squares. The board pieces use puzzle like connectors that snap fit together.

## Processing
## Prepping Parts
Remove any stringy bits and pieces from the parts. Use a hobby knife or flush snips. Clean out the cavities for the legs as they may have overhanging areas.
## Rotary Tumbler
We recommend using two different rotary tumblers. This helps speed up the process and avoids mixing and blending the two materials.
## Tumbling Medium
Use screws as the medium. Steel screws for bronzeFill parts and Brass screws for copperFill. Using different metal screws will differentiate the tones.
## New Screws
You’ll want to use new screws - Old screws that are worn out will not give you as much abrasion.
To get this amazing finish, tumble each part for about 8 hours. So it’s best to do it over night.
## Health & Safety
Be sure to tumble in a well ventilated area, wear proper breathing mask and gloves for safety.
## Tumbling Tips
You’ll have to tumble each part separately to avoid any damage during the tumbling process.
You can toss the part back in if the surface isn’t completed polished. Remove any artifacts and clean the parts free from any left over dust.

## Assembly
## Adhesives
Use adhesives such as E6000 or super glue to permanently bond the pieces together. The tolerances in the parts have a 0.2mm clearance for parts that need to be connected.
## Assembling Players
Insert the legs into the body first, then apply glue to the base. Be sure to align the legs by inserting them into the slots. Inserting the legs into the body before gluing helps properly align the legs.
## Assembling Board
These have tight tolerances which gives the board a bit of flexibility but enough rigidity to move around.
Assembly is like a puzzle game that doesn’t take too long. Simply snap them together. Each square is a standard 5cm piece which makes a full size 40 x 40cm chess board. The chess board requires no glue and everything just snap fits together.

## Play
## Game On!
Setup the pieces for each player and get yourself a worthy opponent.
## Storage
If you printed the players in metal filament, you should store them in a dry air-tight container to avoid the copper from oxidizing or getting dusty. The chess board can be disassembled and storage away in zip-loc bags or boxes.
