#saintflint nema17 need only 2 625 bearing
Good to see the little brother alive! With those colors, it’s almost like in a candy shop!
A fablab for we person are candy shop
could the NEMA17 version also use 625zz bearings?
No I’m in fault nema17 bearing 608 nema 14 625
Is there a reason why the NEMA17 needs a 608?
Elliot because saint are an evolution of #flintfeeder and him use 608 nema14 no permit this bearing for this we decide to use common bearing used in other project too the 625.
in anycase i feel you can modify onshape design for use 625 on nema17 too… @Michael_Memeteau can confirm it?
@Elliot_Foster In theory, it should totally work (they’re smaller). The other way around wouldn’t be possible. However:
- That’s what I had around;
- The larger radius make of a flatter area of contact, helping not to go into “grinding mode”
Now if you’re asking me to make a 625 version for NEMA17, I’m starting to get a kind of a problem:
Looking at the variables involved:
- NEMA 17 or 14
- Bearings 608 or 625
- 1.75 mm or 2.85 mm
That’s already make 8 possible versions!!!
The easier would be for you to get your feet wet with Onshape and change the required dimension in the drawing. That’s not difficult…
Up to the task?

Alas, @Michael_Memeteau I am probably not up to the task. If/when I get a moment, I might take a try at a rewrite in openscad, though… that’d make different parameters very easy to support.
Your design is beautiful!
Guy’s stay in upload video…can move softly ball lock we using for close labs
@Elliot_Foster With such compliment, you just won yourself the variant you were asking for…
It’s not so nice, because the bearing are now flush inside the body of the extrusor, but that’s a matter of taste.
You can have it here (pictures and stl)
This is exactly where I think openscad is a little short when it comes to design.
In a near future, onshape should comes with variables. We should then get closer to the best of both world.
Beautiful again, @Michael_Memeteau … And yes, openscad with such nice little details would be tricky indeed. Really, the conical thread is the thing I’m thinking through at the moment.
