I was asked to create and print a replacement handle for an Brewista electric kettle - here it is available to everyone.

First of all, definitely do not use standart PETG or PLA. Naively, I tried to make a replacement from PETG, and even though everything fit perfectly, the handle couldn't withstand the heat, and the threaded inserts literally slipped out.

The model is prepared for threaded inserts - I personally use inserts from CNC Kitchen. Here are the links to purchase/insert dimensions:

Given that the kettle's body is metal, you should consider the maximum possible temperature - which is very close to 100°C. Suitable materials for printing are likely ABS, ASA, or possibly extremely durable specialty materials that operate in this range.

As a last alternative, there is heat annealing – I personally have no experience with it, but I've seen a few videos on the topic. In any case, the final decision is up to you! For example, Fiberlogy HD PLA, which I’ve read has heat resistance up to 140°C after annealing in an oven.

I am attaching the instructions for Fiberlogy HD PLA, from which I personally draw information:

Print your project.

Print temperature: 200 - 220 °C
Bed temperature: 50 - 70 °C

(Heating the bed is not necessary if you are using pads, tapes, or adhesives that enhance adhesion.)

Allow the model to cool down after printing (with supports and raft still attached).
The print should be placed in the center of the chamber (oven), evenly spaced from the heating elements inside.
Gradually heat it to a temperature of approximately 80 °C.
Anneal (bake) for about 15 minutes at 80 °C.

WARNING: The temperature in the chamber (oven) must be maintained precisely.

We recommend monitoring the temperature with a suitable digital thermometer inside the oven. The print needs to be watched during the heating process. For large prints, you may gradually increase the temperature to 120 °C or extend the annealing time.

After annealing, remove the print along with the pad it was placed on in the chamber, and avoid touching it until it cools down (to room temperature).
Remove supports and raft.
You can now use the finished product, which has gained mechanical strength similar to ABS and heat resistance up to 140 °C. The model may soften at such high temperatures but will not melt and will hold its shape.

GOOD LUCK PRINTING!
