I dropped my battery powered Hakko soldering iron, and the tip clamp fractured :-(
Fortunately there was enough left for me to see its design, and recreate it in Tinkercad.
UPDATE 24-12-2017 part verified working OK, after some minor redesign. STL updated.
A temperature resistant plastic such as PETG or ABS is required. I printed mine in PETG and it's fine.
Supports are pretty much required no matter how you orient the part.. I recommend printing it narrow side to the bed, so that the supports to break off are on a relatively strong section of a part.
The tolerances are very tight and it's almost certain you will need to clean the three clips in the mount to ensure they are clean right angles. You may need to play with filament flow rate (and possibly size percentage) to get the holder printed completely snug with your printer.
There are three things to verify with the clamp, once cleaned up:
- the part with three clips fits into the soldering iron and can lock into place.
- the bottom of the tip fits properly, with the lower ring of the iron tip fitting snugly inside (see second assembly picture)
- the tip itself fits through the hole in the mount. It may be a bit too tight, depending on how tight you might be able to press it in, or you might need to print at a slightly higher size like 100.5 or 101%.
Apart from that it works just like the original clamp.
