Goal Zero Lighthouse 250 Crank Arm Part

I found an abandoned Goal Zero lighthouse 250 at a camp site. The crank arm was broken. But still charged with usb... so I kept it.
Finally got around to tearing it down to find the broken part. It was this little cylinder part that connects the handle to the gear box. You have to take apart most of the top and pry the plastic glass off with a screw driver.

Disclaimer:
Have not tried the part yet. Just made it and ordered a print from a remote printer. Not sure it it is going to fit.
