Remix to fit FX888 soldering iron. Uses M3 x 5 brass inserts instead of captive M3 nuts. Requires 2 x M3 12 hex head bolts.
Printed in PLA as this is not near the hot parts. It clamps around the part you hold with your hand.
If you print this please leave a rating and a photo of your print. I would love to see your print.
Thanks
UPDATE: Thanks to a suggestion from someone who downloaded this I have included a revision of the model v1.2c that includes a flat back surface to aid stability when inserting the inserts.
UPDATE 2: Added a version with 4mm hole for smaller threaded inserts at the request of @Crosslink. STL Filename: Hakko Insert Press v1.2c 4mm.stl
The author remixed this model.
