Start free, upgrade when you need more power.
Free
Explore AI-powered design. Iterate freely — credits only used when you download.
Maker
Full design power for serious makers. Engineering-grade AI for functional parts.
Engineer
Maximum capability for complex projects. Opus-grade AI for multi-part assemblies.
One print credit = one STL download. You can iterate freely with the AI — refine dimensions, change materials, ask for modifications — all for free. A credit is only consumed when you download the final STL file. Credits reset each billing period and do not roll over.
Free and Maker users get Claude Sonnet 4.6 with extended thinking — fast and capable for most designs. Engineer users get Claude Opus 4.6 with extended thinking — the most powerful model for complex multi-part assemblies and engineering-grade geometry.
Finite Element Analysis simulates real-world physics on your designs, showing stress distribution and safety factors. This helps ensure your parts will work in production. Available on Maker and Engineer plans.
Free users get Quick Prints — fast templates for stands, organizers, and clips. Maker adds Engineering with Claude for functional parts like enclosures and brackets. Engineer unlocks everything, including Multi-Part Assembly for gear trains and snap-fit mechanisms.
Yes! Credit refills are available for $10 (25 credits) regardless of your plan. These are added on top of your monthly allowance.
Yes, you can cancel your subscription at any time. You'll continue to have access until the end of your billing period.
