I think there are too many mentions of Chinook in this thread. Not a good idea to speculate on the make if you dont know what make it is.

I have 3d printed quite a lot of stuff with consumer grade FDM printers.
Absolutely NONE of it is structurally good enough to make a mast box out of by itself. ie MASS printed plastic part in the style of an injection moulded chinook box. In my view this would be an absolutely terrible and unsafe idea. There are other printing processes and qualities of machines that can give much greater structural strength. I have not come across any plastics ones that can do the same strength as injection molding though, not in "practice" anyway.
That said perhaps the 3d printed part was used in conjunction with some composites to make the track- this then isn't necessarily intrinsically bad, it could be a bad implementation of a possibly successful idea.
What i have learnt, to my cost is that its a bad idea to practice on your customers, as when it goes wrong, its your stuff that looks ****.

Who cares about the customers anymore?

I do.

My understanding is-
It is a 3d printed box that has failed.
It is NOT a chinook box that has failed.
It has been suggested that a chinook box would have been superior and not broken.

1st post "Box is likely Chinook." Soon after someone else "Is there a problem with Chinook boxes ? " It snowballs into misinformed doubt.
BTW, dont forget to make sure your mast track is strong enough to cope with the possible rotational force applied by a bendy tendon/UJ.
