ELNA Elnita 250 Replacement Gear

thingiverse

Sewing machine by ELNA, model Elnita 250. Gear inside the metal cover for switching the type of stitches. Pictured showed are the original part, crazy glue together and the green part is my first try (space between teeth not even). Final part (stl available to download) is my second try. I would highly recommend to modify (I use Tinkercar) the STL so that the wall for the metal connection with the knob/shaft won't bend like my second test did (already install in the machine). And almost forgot, it is made almost like the original, meaning that you have to insert the metal knob (align the hole to be able to secure it in place with the shaft) like an heat set insert. I just used an old soldering gun for this. Take time to heat it up since it's a big peace of metal, but I can finally use it again. Have a nice morning!
