Before you hit Submit

All five steps look complete. Ready to send.

Ship received.

If your build is under 6,000 parts, it's already live in the public catalog. Larger builds head to mod review — typical turnaround is 24 hours, and you'll get a Discord DM either way. You can find it in My uploads on your account anytime.
