Repair Parametric Fusion360 Box

My stackable, adjustable storage box was built as a fully-parametric Fusion 360 assembly, but a tangle of broken links now keeps it from updating cleanly. I’ll give you the original editable file—once you walk me through the simplest way to upload or share it from my local drive—and I need you to:

• Re-establish every internal reference so the model updates without errors.
• Convert the existing 3⁄8″ coarse lid-mount bolt and standoff to an Acme-style thread that’s harder to cross-thread.
• Let the slotted face (with its mating holes) swap from one end of the box to the other through a user parameter rather than manual edits.
• Confirm the main body remains printable in ASA while the integrated seals remain suitable for TPU.
• Document, step-by-step, how anyone can adjust key parameters—height, length, wall thickness, thread size, seal clearance, number of holes etc... end-panel selection—directly inside Fusion 360.
