Yeah I came to the same conclusion when working on a shell for the walker. Just seems easiest!

I went a little further with the shell. This time the inner ribs are CAD drawn and printed on paper. The shell is from paper and 2D bend only. So I can use stiff paper, fabric or thin 3D printed plates to cover it later.



Started to build the inner structure by 3D printed parts. Have to think about how to connect all this:

I found some good curves for the ribs:



Here glued together with paper strips - will replace this with plastic of cause.



Covered with paper to verify the outer shape.
No concept for tail and head now...


Please notice - this is a smaler eye module with smaler servos.

Hello friends,

I started to print the R2 body of macropede. No big new things but still some new ideas about strength and printability. I also can mount the muscels in a propper manner now - even in two alternative positions. Also a support for the eye module is included plus some spare posts for mounting brain and other bowels.



Yes, this are two parts...
Next will be the design challenge for the front and aft section...

Just a little detail. Now you can use the wrench for the M3 nuts without problem at all 32 positions! Here it is not possible to integrate a support for the nut into the structure because you need this to adjust the bearing play and to secure it by tighten the nut.


PS: bad print because of lousy ABS...

Actual package:


The eye mount is not redesigned to fit the new base for now.
