This is the AMS lite top mount but you dont need to pay $7 to ship a couple of screws. The wiki states what the screws are in the $2 kit, and you can go to a local hardware store and pick up 12 M3*10 screws. Since theres no threading in the holes they go in, you can use what ever thread spacing you can find. The other screws in the bambu kit act as a hinge, and I just added a hinge into the part
The author remixed this model.
I modified the part that clips onto the top of the printer, this means you dont need the relatively obscure screw to complete the hinge. The STL is just the modified part, not of the other pieces.
