When the repair completes, you’re taken to the repair detail page where you can view the fix report, compare before and after, and download your print-ready model.
Not sure which preset to use? Start with Custom — it works well for most models. You can always re-repair with different settings.
Your first 2 repairs are free. After that, you need a subscription to continue repairing. See Plans and pricing.
