Frequently asked questions
What soldering iron do I need?
The tip fits irons that accept compatible tips, such as common Hakko-style bits. Check the thread or shank details in the photos.
How do I install the inserts?
Heat the insert with the tip and press it into a pilot hole slightly smaller than the insert. Keep it straight until the plastic cools.
Do they work in PLA and PETG?
Heat-set inserts work well in PLA and PETG when the pilot hole is correct. Use a lower iron temperature than the plastic's print temperature to avoid melting too much.
