Modular Golf Simulator Enclosure Design
Budget: $750 – $1,500 USD
I need a mechanical design engineer who can transform my dimensional outline for an 8' × 12' × 12' indoor golf-simulator enclosure into a complete, build-ready package. We are developing a modular indoor golf simulator enclosure and floor platform constructed from 4′×4′ welded aluminum frame panels (40 mm × 80 mm rectangular tubing, 1.2 mm wall thickness).
The system must be lightweight, durable, and simple to assemble, with compact packaging for shipping and professional indoor presentation.
Each wall, ceiling, and floor section will connect via bolts and alignment rods.
A front extension beam will support the overhead launch monitor sensor and projector, and the floor will feature a built-in hitting-mat insert for realism and convenience.
We need an experienced mechanical design engineer with expertise in aluminum structures, modular design, and manufacturable assemblies to complete the full CAD and fabrication package.
Scope
1️⃣ Frame Structure
Frame: 40 × 80 mm aluminum rectangular tubing, 1.2 mm wall thickness
Panels: 4′ × 4′ (≈ 1.22 m × 1.22 m), TIG-welded 45° corners
Walls: Two panels stacked vertically per side (total height ≈ 2.44 m)
Ceiling: Three 4′ × 4′ panels bolted together to create a 3.6 m-wide roof
Support beam: Central ceiling beam (3 sections joined by bolts) to prevent sagging and simplify shipping
Connections: Bolt-through or sliding-rod alignment for quick and repeatable assembly
2️⃣ Front Extension Beam (Sensor & Projector Mount)
Profile: 50 × 100 mm aluminum tubing (5 × 10 cm) for added stiffness
Length: 48″ – 60″ (1.22 – 1.52 m) forward from the screen
Mounted to the top-front edge of ceiling with reinforced brackets or gusseted sleeves
Must support both projector and overhead launch monitor sensor Include:
Hidden cable routing (power / HDMI) Rigid, vibration-free mounting
Quick disassembly for shipping
Optional cosmetic cover or side plates
3️⃣ Upholstered Wall Panels
Attached to frame with L-brackets and screws
Composition: 0.8 – 1.0 cm plywood base
5 cm high-density upholstery foam
Synthetic leather or fabric covering
Must sit flush inside aluminum frame for a professional interior finish
Panels should be replaceable or serviceable
4️⃣ Floor Platform (With Hitting-Mat Insert)
Structure: Aluminum sub-frame supporting 1.8 – 2.0 cm plywood decking
Surface: Putting turf throughout with a dedicated hitting-mat insert (mandatory)
The hitting-mat area must: Sit flush with the surrounding turf Be removable/replacable/Handle repeated club impact
Floor system should be modular for transport (6-9 sections)
Must support realistic stance, ball lie, and putting performance
Integrate cleanly with wall base frames
5️⃣ Assembly Method
Panels connect with M8 – M10 bolts, washers, and locknuts
Use alignment dowels or extruded rods for square fit
Minimal visible hardware on the interior
All components designed for tool-light assembly (Allen wrench or spanner)
• Structural Frame – 4' × 4' modules built from 40 mm × 80 mm aluminum rectangular tubing (1.2 mm material thickness).
• Projector Beam – single 50 mm × 100 mm member spanning the hitting area.
• Floor Platform – integrated base framing that accepts a replaceable hitting-mat insert and keeps the hitting surface flush with the surrounding platform.
• Upholstered Panels – detachable wall and ceiling panels skinned in synthetic leather or upholstery fabric over foam cushioning, fastened so they can be removed for maintenance.
• All design work is for indoor use only.
Deliverables
1. Fully detailed engineering drawings with dimensions, tolerances, and weld/fastener specifications.
2. 3D CAD models (STEP + native format) showing every sub-assembly: frame, projector beam, floor platform, and each upholstered panel.
3. Bill of materials and cut lists for aluminum profiles, hardware, upholstery layers, and foam.
4. Exploded-view assembly guide illustrating panel order and mounting method.
5. Basic load/stability check to verify the frame will stay rigid during play.
Please base your work on standard manufacturing practices for aluminum extrusion and make sure all components can be sourced or fabricated without exotic tooling. CAD can be done in SolidWorks, Fusion 360, or a comparable mainstream platform—as long as export to STEP is included.
I’m ready to answer clarifying questions quickly so you can move straight into modeling and drafting.
