I separated the main STL file made by original creator (whisperit) https://www.thingiverse.com/thing:6364915.
I also modified the size of the SSD cover to support heatsinks. You should print the backplate standing up and use supports and support blockers.
You will need these brass insets M2x3x3.5mm and also soldering iron with small tip (small enough to hold the insets) or a 3d pen (or you can use something else to hold insets while you heat them up to melt the parts) to assemble the stock hinge with the kickstand. You can buy them from here: https://www.amazon.com/dp/B0B8GN63S2?psc=1&ref=ppx_yo2ov_dt_b_product_details
