Gearbox’s have been test Printed a few times to work out any bugs … still a couple of Minor bugs to fix—I wanted them to be Print&Play ,,,, No to very little clean-up work needs to be done just screw and bolt them together so fine tuning is everything– I’ve got some time off so want to get this section finished ,,,,as you can see the design looks the same as the originals but there not,,, they are not backwards compatible with other Gearbox’s parts,,, but they are backwards compatible for the framing – ,,, once there finished I’ll do quick video of the assemble procedure,,, this has been an awesome project to work on,,,,
