I often encounter a circumstance that during multiple print projects that I loose track of which files to print next.
These easy to snap on and off temporary SD card holders can help organize the sequence files to be printed.
They can also be “color coded” in a way that all files existent on the card is to be printed in matching filament color reducing the number of times of filament changes during a long, multiple parts project.
The author marked this model as their own original creation.
