Introduction
This accessory will be used in one of my projects currently being developed for the PRUSA Mk4. Although I'm aware that there are several solutions for this purpose, I have chosen another option that will fit into the aesthetic I have planned.
And is extremely easy and fast to print.

How to use
The usage is simple:
- Unload the filament.
- Increase the temperature of the nozzle to 250ºC to clean any material remains.
- You may want to clean the nozzle with a metallic small brush (Danger: Very hot nozzle, don't touch it)!
- If you have a silicon sock, be careful, it will be better to remove it first with the nozzle cold.
- You may want to clean the nozzle with a metallic small brush (Danger: Very hot nozzle, don't touch it)!
- With the nozzle cold (below the glass transition temperature of the material you will use for printing the key) and ensuring not to burn yourself; use the key to remove the nozzle.
- This should be done following the instructions provided by PRUSA
