Pinch roller lever for vinyl cutter plotter (Rabbit). These break very easily. This is a very close, but not exact copy of the original. This is from a China manufactured machine branded "Rabbit" and is possibly used on several plotters and printers.

Printed in PLA with supports. Some cleaning up required.
It's very simple to fit and it is not necessary to remove the carriage or rail from the machine, but for clarity:
Release the tension from the pinch pressure spring if it is not possible to use the broken lever
Remove the small screw in the top of the carriage adjacent to the spring
The (white) plastic dowel pin will push through the carriage. It is a very tight fit. Tools were needed.
The inside of hole in the new lever may require sanding smooth to allow free rotation round the dowel pin.
Ensure that the small intent in the outer circumference is clean
Note that this lever hole is approx 1mm wider than the width of the lever.
Re-assembly is the reverse. Note that the screw hole in the pin must align with the hole in the carriage.
