Subreddit rules check

Can you promote here?
Promotion is allowed only with moderator permission (or inside designated threads). A short, honest modmail before posting costs two minutes and functions as a safe-conduct pass; skipping it is the most common avoidable removal.
From the rules · Rule: “No Dust Collectors” — decorative objects that do nothing are removed.
Links
The rules clearly allow links. A plain-text mention still often outperforms a URL from a young account.
What this community rewards
Dominant post formats: showcase, guide, discussion
Title: short problem → solution (e.g., “I was tired of X — printed Y”). Use first person, include photos, brief build notes (filament, printer, settings), and a link to the STL or writeup. Keep post body concise and practical — explain use-case, fitment, and durability. Posts that solve real problems and include pics/files get upvoted; decorative “shelf-only” prints get removed.
Arriving in the local format matters: cross-posting the same text everywhere reads as tourist instantly. The wider method is in the Reddit playbook.
Classified mechanically from the community's published rules and recent top posts, last checked August 2026. Rules change and moderators have the final say: verify at r/functionalprint's rules page before posting anything that matters.
Thread Otter checks this before every send
These profiles power the product: promo-banned communities never receive a promotional draft, drafts arrive in the local format, and a fact-check gate plus human pacing protect the account doing the talking.
