The maker's toolkit.
Free to use. Yours to keep.
Check a model, price a part, pick a material, generate a gear — across 3D printing, CNC, laser, sheet metal, casting, electronics and textiles. Every tool runs in your browser, no signup, nothing uploaded. A full maker workshop layer is launching soon.

Questions
Are the tools really free?
Yes. Every tool on this page runs entirely in your browser with no signup and no cost. Files you load — like an STL — are processed locally and never uploaded.
What will registering as a maker include?
The maker workshop layer is launching in stages. Earnings and escrow-protected payouts are live now via the marketplace.

Join the waitlist to be notified as each piece goes live.
Which disciplines are covered?
3D printing, CNC machining, laser cutting, sheet metal, metalwork, casting and molding, electronics and PCB, and textiles — with new tools and markets added regularly.
Does it cost anything to be a maker?
Creating a maker account and using the workshop tools is free. The Spool List earns through a transparent fee on completed, escrow-protected jobs.
