Zebra GXT Printer Ribbon Knobs

thingiverse

This is a replacement knob for Zebra GX/GT printers, ensuring secure ribbon positioning. In our workplace, we frequently use these models; the original tabs often broke. To resolve this issue, I measured the part and created a durable substitute. Initially, I used PLA filament, but it was prone to breakage. For enhanced durability, consider using ABS instead. Alternatively, I designed a tab-less knob with a stopper for PLA filament, which performs just as effectively.
