The woven grass game controller merges high-tech Bluetooth peripheral functionality with ancestral artisanal craftsmanship, wrapping modern circuit boards in sustainably harvested, tactile natural fibres.
Material Specifications
- External Shell: Hand-woven sweetgrass, rush, or abacá natural fibre matting treated with a flexible stiffener.
- Internal Housing: Lightweight 3D-printed PLA core or rigid felt frame to secure the Bluetooth controller module and rechargeable lithium battery.
- Electronics: Compact Bluetooth game controller PCB, tactile push buttons, mini analog joysticks, and a USB-C charging port.
- Binding & Thread: Waxed linen cord or heavy-duty synthetic sinew for structural whip-stitching along the outer rims.
Toy / Peripheral Measurements
- Dimensions: Medium-size ergonomic controller form factor—Total length: 15 cm, Width: 10 cm, Depth: 5 cm.
- Component Pieces: Top Control Plate, Bottom Grip Housing, Left/Right Handgrip Shells, and Internal Circuit Mount.
Pattern Drafting Steps
- Step 1: Baseline Grid & Ergonomic Contours
Draw a centre horizontal line measuring 15 cm. Plot vertical symmetry lines at 0 cm (left grip centre), 5 cm (left thumb-stick zone), 10 cm (right action button zone), and 15 cm (right grip centre). - Step 2: Top Control Plate Drafting
Draft a curved oblong shape measuring 15 cm in width by 7 cm in height. Contour the top edge with a gentle inward dip to accommodate shoulder bumpers, and cut circular port holes for dual analog joysticks at positions (3.5 cm, 3.5 cm) and (11.5 cm, 3.5 cm). - Step 3: Bottom Grip Housing Drafting
Draft a matching lower shell piece 15 cm wide with expanded drop-down contours extending downward by 3 cm on both the left and right outer ends to fit ergonomic palm grips. - Step 4: Side Shell Gussets & Internal Mount
Draft a 2 cm wide continuous side perimeter wall strip to bridge the gap between the top and bottom plates. Draft a flat internal mounting plate matching the inner cavity shape (13 cm x 5 cm) to anchor the Bluetooth PCB. - Step 5: Seam Allowances
Add a uniform 0.6 cm (1/4 inch) inward turning allowance along all edge boundaries to tuck under the raw woven grass fibres. Punch preliminary hole guidelines spaced 0.5 cm apart along the perimeter for whip-stitching.
Construction Instructions
- Step 1: Preparing the Woven Panels
Cut out the top plate, bottom housing, and side gussets from stiffened woven grass sheeting. Apply a coat of fabric stiffener or diluted PVA adhesive to the reverse side to prevent unraveling when cutting joystick and button apertures. - Step 2: Securing the Internal Mount
Glue the 3D-printed or felt internal structural frame to the inside of the bottom grip housing using flexible craft adhesive. Mount the Bluetooth controller circuit board securely onto the internal standoffs. - Step 3: Assembling the Outer Shell
Align the top control plate and bottom grip housing with the side perimeter gusset inserted between them. Guide the joystick shafts and protruding buttons cleanly through the designated faceplate apertures. - Step 4: Edge Whip-Stitching
Using a large blunt tapestry needle and waxed linen cord, lace the components together along the pre-punched perimeter holes using a continuous whip-stitch or blanket stitch to lock the woven edges tightly. - Step 5: Pairing & Testing
Connect the device via Bluetooth to your target platform, testing all tactile switches, directional pads, and analog inputs for smooth responsiveness.
Finishing Tips
- Apply a thin, matte spray lacquer or clear acrylic sealer over the exterior woven grass to protect the natural fibres against hand sweat and wear during gaming sessions.
- Sand any rough interior frame edges smooth prior to final assembly to ensure the internal wiring harness remains uncompromised.
