I never liked that the X1C only opened 90 degrees. It makes it difficult to work inside the machine with both hands. This hinge replacement allows the door to open up 180 degrees.
It reuses the screws for the top hinge, and glass door (which is installed on the inside of the door, instead of the outside). You will need longer screws for the bottom hinge. However I designed it so that you can use the medium sized shipping screws that come off the Bambulab X1C during installation.
You can use this guide for how to remove the old hinges and install the new hinges. It will obviously differ once you get to reattaching the door.

Its not a perfect design and I would love to see someone with more talent redesigning the model to work better.
Update: V2 version on Printables. Uses original bottom screw instead of shipping screws, removes/reduces gap between top arm and top mount, modified gaskets to add more protection to the glass, and allows for binding screws to be added to the build mid-print.
