They don't make the HS-35 anymore they replaced them with the HS-40 and the case size is not the same.

HS-35 = 18.6mm x 7.6mm x 15.5mm HS-40 = 20mm x 8.6mm x 17mm

@smiller29 You are making great progress. I will add this bit of wisdom I learned when building my inmoov and it's not really my wisdom, it is Gaels. Putting all the servos in the hand will add a lot of weight to it and when you get your bot moving and the arms swinging you will see that it is really delicate. That is why he had the servos in the forearm. I tried many hand designs but the lack of precision during movement and the fragility of the arms really limit things. Not trying to be a downer, just passing that on.;)

Perry,  always good to get the feedback and I may be going down the wrong path but I really feel this is going to work better in the long run.  Well I hope so.

I am also working on a design to replace the shoulder and arm assembly with planetary gear systems that should make them stronger as a side project.  Going forward right now I will build him out with the standard parts as I have already printed them, and have the servos for them.

Gaels work is great but me being who I am makes me want to tinker and tweak stuff.  It maybe a complete fail or a complete success only time will tell.

I totally respect this path. We will never evolve and find better ways unless we try different things. At the very least, a fail will grant knowledge if your open to it. I've done so many prototypes that have failed but tried to learn from them. When that one works that does something no one else has done (that they said couldn't be done) it's such a thrill! Good luck and keep reaching.

I love the Teflon tape idea he uses. I'll have to keep that in mind!

Love this post / build! Great list of stuff you have used, tools and electronics. It's really helpful for some one (like me :-)) who is starting out.

Cheers and look forward to more posts!

Well I am happy to report the MRB1 Butt has been printed !!!!  YAY!!!!  After  1 and 1/3 spools of filament and 3 days of printing we have one pricey Inmoov sugar plum LOL.  Don't ever want to print another one of these...  Just need to solder the pot for the waist and mount the butt to it after that we add the legs.

I went to the store and got the threaded rod for the legs just need to paint them and put stuff together....
