Llaveros de nombres - Keychains

You simply need to pause the print job, remove the filament and add the one you want. To know where to change the filament, you have to enter your 3D software - I use "Cura2" in my case - segment the design, then go to preview mode and on the right side there will be a bar that allows you to lower it to see how the layers of the print are being made.
