Project Ideas

Business

Small-Part CNC Cutting Service

Offer fast-turnaround through-cutting and profiling of small parts in plywood, MDF, acrylic, and HDPE up to 1/2". The 1/8" upcut allows tight inside radii and dense nestings, ideal for makers, schools, and sign shops needing short runs.


Custom Inlay Production

Provide matched pocket-and-inlay sets for woodworkers and gift shops. Cut pockets and corresponding inlays with the same tool to ensure perfect tolerance. Sell ready-to-glue kits for cutting boards, boxes, and plaques.


Acrylic Letters and Stencils

Produce polished-edge acrylic letters, logos, and reusable stencils. The solid-carbide, double-flute upcut manages chips and heat for clean edges; upsell adhesive backings, mounting templates, and bulk discounts to schools and event planners.


Organizer and Insert Line

Launch a line of modular drawer and case inserts (e.g., tool trays, camera gear fits, hobby organizers). Batch-cut with the 1/8" bit for detailed pocket geometry and offer custom-fit services via customer-supplied dimensions.


Router Templates for Woodworkers

CNC-cut precision acrylic or MDF templates—circles, curves, furniture parts, and joinery guides. The upcut bit yields accurate inside profiles and smooth edges; bundle sets and sell online to luthiers, cabinetmakers, and DIYers.

Creative

Inlaid Cutting Boards

CNC pocket intricate inlay designs into hardwood cutting boards using the 1/8" upcut for crisp, chip-free pockets and clean bottoms. Then cut matching inlay pieces from contrasting wood or acrylic for tight, repeatable fits thanks to the solid carbide edge retention.


Layered Topographic Wall Art

Stack contour layers cut from Baltic birch or colored acrylic. The double-flute upcut clears chips on deep profiles and tight radii, while the 1/8" diameter enables detailed coastlines and elevation lines.


Parametric Earrings and Pendants

Design geometric or nature-inspired jewelry and cut them from hardwood, HDPE, or acrylic. The upcut spiral keeps small parts cool and ejects chips, reducing melting in plastics and fuzzing in wood; add light chamfers post-cut for a finished look.


Interlocking Puzzles and Brainteasers

Produce precision jigsaw puzzles, burr puzzles, or gear mazes. The 1/8" bit excels at tight inside corners and consistent kerfs, allowing snug fits and repeatable batches with minimal sanding.


Custom Drawer Inserts

Pocket out fitted tool and utensil trays from plywood or HDPE. The upcut geometry gives flat, clean pocket floors and efficient chip evacuation on deeper cavities, ideal for crisp engraving and shallow labeling too.
