hotend is run by one person, not a call center — but every email gets read, and we usually reply within 24-48 hours.
Write to us if…
- You spotted a wrong spec. Our promise is data verified against official sources; if a number looks off, tell us (ideally with the source) and we'll fix it — with thanks.
- You can't decide on a printer. Tell us your budget and what you'll print; we'll point you using the same data we publish, no hype.
- A tool breaks or lacks something. The tools (lithophanes, cut STL, text to STL…) run in your browser; if something fails, tell us your browser and roughly what file you used — or request the feature you're missing.
- A printer is missing from the catalog. Name the model and we'll add it to the verification queue.
- Press or collaborations. Rankings aren't for sale and neither are reviews — for everything else, let's talk.
