OpenSpindle is a manufacturing marketplace for custom parts. Upload a CAD file, drawing, or BOM and we route the job to independent machine shops and fabricators set up for that part and quantity, then return itemized quotes in about 48 hours. CNC machining, turning, sheet metal, laser, waterjet, welding, 3D printing, molding, and finishing, from one prototype to production runs. Quoting is free. Based in Austin, Texas.

Tom and I started OpenSpindle because we kept running into the problem of finding the right manufacturing partner that was harder than it should be. What started as an effort to simplify sourcing for custom construction projects quickly expanded when we realized hardware startups were facing the same challenge: spending countless hours finding shops, comparing quotes, and managing vendors. We decided to build OpenSpindle around that problem by making custom manufacturing faster, simpler, and more accessible. Today, we’re helping hardware teams source parts across CNC machining, fabrication, 3D printing, carbon fiber, plastics, and metals, giving founders more time to focus on building instead of chasing suppliers.

Congrats on the launch! A marketplace connecting hardware startups with vetted fabricators is such a valuable idea — wishing you tons of traction 🛠️
