Zebra GXT Printer Ribbon Knobs

thingiverse

This is for a Zebra GX or GT printer. This is the knob that holds the ribbon in place. We use a lot of these printers at work, the tabs kept breaking on these knobs. So I got one took the measurements and made one. The ones with the tabs I made also seemed to break easily, I was using PLA filament. ABS may work better for with this print. For PLA Filament knob, I created a knob without the tabs and used a stopper instead works just as good.
