Modify Legion Clam STL Design

I have an existing Legion Clam STL design that was made for the original Lenovo Legion Go. I need it modified for the Legion Go 2. The top half should securely hold the Legion Go 2 tablet while maintaining access to vents, USB-C ports, speakers, and buttons. The bottom half should hold the original detachable Legion Go 2 controllers in their normal gaming positions. The controllers should remain removable and should not require any modification to the electronics. The final design should fold closed like a Nintendo DS/GPD-style clamshell using metal hinges. Adequate clearance must be provided so the joysticks do not contact the screen when closed. Deliverables: * Modified STL files * STEP/Fusion 360 source files * Recommendations for hinge hardware * Design suitable for PCBWay 3D printing.
