It appears that bricklink / LEGO is trying something new which allows you to purchase the instructions and all the parts you need for someone else’s MOC. It is probably expensive, but now computing power can optimize how to get all the parts you want.
Regardless, I am more interested in the idea of putting instructions on bricklink. Has anyone in the LUG made their STUD.IO instructions available on bricklink? If so, can it be done independently of having an open bricklink store?
