In their Infinite wisdom, Creality have made the K2 Plus chamber heater to blow hot air directly onto the printed part. On taller prints this leads to leading to part warping and bed deformation.

The Temperate Heat Deflector diverts air away from the printed part, improving print quality, especially on taller prints from engineering filaments.

- Improves print quality with engineering filaments

- Optimised for low filament use

- Compatible with the [internal waste chute](https://www.crealitycloud.com/model-detail/creality-k2-plus-internal-waste-chute) mod

Internal waste chute

- Avoids blowing hot air on sensitive parts of the enclosure

- Allows your K2 Plus to be superior to the other inferior K2 Plus printers

What you will need

Parts and materials

- 4x [M3xL4xOD5 threaded inserts](https://s.click.aliexpress.com/e/_c3yscP9r)

- 4x M3xL8 flat head screws ([hex](https://s.click.aliexpress.com/e/_c3a5SLtR) or [Torx](https://s.click.aliexpress.com/e/_c4VnwZ3x) version).

- Use a filament that can withstand high temperatures produced by the heater - around 135deg C. Good choices are [PA-12CF](https://s.click.aliexpress.com/e/_c2xE1y0z) or Creality's own [PPA-CF](https://store.creality.com/products/ppa-cf-filament-1-75mm-1kg)

- Optionally, some scotch tape or a double sided tape to hold the deflector in place while securing it with screws.

Tools

- [T8](https://s.click.aliexpress.com/e/_c3OM5wSv) or [H2.0](https://s.click.aliexpress.com/e/_c3eRRymZ) screwdriver

- Soldering iron with an adapter for threaded inserts. A separate inexpensive corded iron similar to [this one](https://s.click.aliexpress.com/e/_c32OGgyN) works great for small inserts. For larger inserts, I use [Alientek T90B](https://s.click.aliexpress.com/e/_c3uPE1GD) soldering iron with a [C245 adapter](https://s.click.aliexpress.com/e/_c4liXgQt).

Instructions

- Print the deflector using the provided print settings

- Install 4 threaded inserts.

- Remove the back panel by following [Step 2 of this guide](https://store.creality.com/blogs/tutorial/creality-k2-plus-mainboard-replacement-guide)

- Remove the four self-tapping screws that secure the stock heater cover. The screws are in the corners around the heater assembly. Refer to the picture below for the location of the screws.

- Install the deflector with its vents facing to the left (away from the cable drag chain) and secure it with 4 M3xL8 screws from the back of the printer. You can use a piece of a double sided tape to secure the deflector temporarily while securing it with the screws.

- Reinstall the back panel.
