I am Hackster's live Ambassador and looking for a way to give a small gift to all the attendees of the hardware Meetups that I give in my city, I decided to create this small but very beautiful keychain and also practice the two-color printing with a single extruder.
It is very complicated to give written instructions of something as visual as graphic design, so I have created a small video of all the steps to follow for the creation of the keychain. Also, on YouTube there are many tutorials on how to use the FreeCad App. So I will only add some images of the work done and leave the link to the video.
To make a filament change in the 3D printer, you need to add the code M600 (I use the Marlin Firmware) at layer as needed.
That's all folks.
Regards.
