. You will need the build videos for this as it is not an easy build.
Due to the large number of parts I have grouped them to plates of parts for my Bambu A1 mini. You can always take these plates and select to separate the parts in your slicer and print the parts one at a time or whatever works best for you.
I started with just wanting to do the walking legs based on modified differential gears that I found on thing-i-verse by otvinta3d. thing:2116304.
I use several Lenths of screws, both 6-23 and 4-40 type. So, if you live in the land of mm and plan to use mm screws you will have to convert.
I use a 1:90 tt gear motor for the waking and a 1:220 for the arms / mouth.
I use 3 AA batteries for power.
I use a slide switch with 19mm mounting screw holes.
LEDs for the chest display and eyes.
Rubber O rings on the feet ratchet wheels.
