- Make two nichrome wire coils (26 gauge) that are approximately 54mm long and have around 40 coils by wrapping the wire around a 3mm wide rod. Make sure there are tails of at least 2cm long on either end of the coil.
- Put a strip of copper tape on either side of all three fired ceramic pieces. One side will be power (red) and the other ground (black). Wire two 3D printer fans according to the electrical diagram.
- Place the ceramic pieces in the case and attach each coil from a long ceramic piece to a short ceramic piece. Wrap the long ends of the nichrome wire coils around the fired ceramic pieces from step 2 a couple of times, and cut off the excess. Wrap the nichrome attachments with jewelry wire or other wire that can be soldered. Make sure to make a strong connection between the nichrome wire and the jewelry wire.
- Wire the coils according to the electrical diagram.
- Glue in the fans and ceramic pieces, and wire an attachment to a 24 volt power source.
- Glue in two strong magnets so that your heater can magnetically attach to the printer.
