Fusion 360 Enclosure Rim Fix

Description

I have a Fusion 360 design of a 12-sided shell / half-cube-like enclosure. The current issue is that the mating rim/edges are not perpendicular/planar relative to the ground, so the other half cannot close straight on this half.

I need a Fusion 360 professional to repair the model properly (parametric, clean timeline) so:

The closing interface (rim) is perfectly planar and/or aligned as required.

The two halves mate cleanly (no tilt), with proper alignment.

Optional but preferred: add alignment features (lip + groove / tongue-and-groove) with 3D-print friendly clearance.

This is a mechanical CAD cleanup + enclosure mating design task.

What I will provide

Fusion 360 file (F3D / Fusion archive) of the current half

Any target dimensions / desired split plane height (if needed)

Intended manufacturing method: 3D printing (likely)

Your tasks (deliverables)

Fix geometry so the mating interface is correct:

Rim is flat (same plane) and/or edges are perpendicular in the correct direction for closure.

Produce the matching other half so the enclosure closes properly.

Add alignment features (preferred):

Lip + groove (or pins/sockets)

Suggested clearance for print (e.g., 0.2–0.4 mm, you can propose)

Provide exports:

Updated Fusion 360 file (F3D) with clean parametric timeline

STEP for manufacturing

STL for both halves (if requested)

Short note explaining what was changed (1–2 paragraphs).

Requirements / Skills

Strong Fusion 360 experience (solid modeling + parametric workflow)

Experience designing enclosures that mate (3D printing tolerances a big plus)

Must keep model editable (no “just mesh-fix” approach)

Acceptance criteria

When assembled in Fusion, the two halves close straight with no visible angular mismatch

Contact/mating surfaces are planar and consistent

Alignment features fit with agreed clearance
