Platform fee
Listing is free. A 12.5% platform fee applies only when a sale happens — it covers card processing, secure hosting and admin. Nothing is charged just to list.
The buyer signs in and pays STL Galaxy securely via Stripe before any file download, so your design stays protected. The platform fee is deducted, then your seller share (87.5%) is paid out through Stripe Connect after the usual hold period (about 7 days once Connect is linked).
In brief: you must own or have rights to the design; buyers get personal-use rights unless you state otherwise; no prohibited or unsafe content; refunds and disputes follow platform policy; and STL Galaxy can remove listings that breach the rules.
