    Wow, great looking actuator. That would be very cool. Maybe for my next build! Ha this will be the one and only for me. Unless I find friends in the area that are going to be paying for it. Have you found issues with using the rose joint or are you just looking for something different? I haven’t ordered any rose joints yet and am waiting for my ball screws still so if you recommend agains the ball joint let me know. Thanks for all your work on this.

    Thanks man, yeah i liked the 3 rod look. was a bit tricky because of the ball nut hole spacing but i managed to still pickup 4 holes on it, just not uniformly. I am trying to find a ball nut that has the 360 degree flange on it without the cut outs, might be better to work with. I've seen them before but now struggle to find them anywhere. Will have to ask around some sellers. Quick question.. Does your base move at all? like lift or anything? I'm probably going to do a similar design base yo yours as well. I do like its minimalist look and feel.

    @pmvcda I'll be very interested to see what you come up with if you make a next iteration, Thats for sure :) I'm fairly happy with mine at the moment but as i want to go longer ballscrews i thought i'd take the opportunity to try out a new design and smooth things out. Why not ey?! :)

    Haha yeah mate, you'll be fine. You just have to pick an idea and stick with it till the end. The rate at which new ideas and designs are formed is hard to keep up with and if you keep changing your plan every 2 weeks you'll never get finished hehe.

    Hey there,

    The ballnut shapes SFI/DFI, SFV/DFV and SFM/DFM should be available with a round flange. Unfortunately a lot of chinese sellers call everything "SFU" even if it is a different shape and the aliexpress/alibaba search algorithms are the worst. SFI1610 is apparently a stepper motor, that has neither "sfi" nor "1610" in its name or description -.-

    Awesome man! Thanks. So SFI1610 is the round flange version? That's what I've been trying to figure out. But like you said aliexpress don't really list anything but sfu. Thanks for the link, I'll hit up the seller for a quote :)

    SFI can be both, round or with one or two flats, it's just the general shape of the nut and has to be specified further. I think evey manufacturer that has one of the three types I listed above in their portfolio should be able to do the round version.

    Well just got my screws today finally! A little over a month to cross the ocean! Ordered the misc hardware so hopefully I will start assembling my first actuator this weekend or next. I have enough plastic parts printed for 3 for now so I figured that would be a good start to see what parts I need and what I need to adjust! The bottom UV joint I noticed silentchill recessed his nuts. I missed that when I did mine prints so I think I might just make a plastic spacer to make up for the nuts. How's your build coming along? Have you started building a frame yet?
