davedarkoI'm trying to replicate the head behaviour of the "my keepon", as seen here [https://hackaday.com/2009/10/29/keepon-eat-your-heart-out/] and so I try to 3D print something that might work. I can't make out if the servos are connected in a 90 or 180 degree angle, so I've added 4 screw holes. These are two parts, printed into each other with a distance of 0.5mm - let's hope that's enough room.
I googled it further and found out that I basically want a swashplate (that's my google term) - with that I'll get an awesome range for shoulders and head! Just imagine the head with some oled eyes and the shoulders attached to this part and I'm almost done. Well, not really. Not at all. The amount of servos used is 3, so like a delta bot basically. Not sure if the shaft has to be fixed or also on a ball joint.

The swash plate needs a ball bearing, I don't know if you want / need to spin the shaft.

I was able to print just that :) the parts are at home and I was out of servos, so I need to get back to it in 3 weeks.

For a quick and dirty solution you could look for a cheap RC helicpoter spare part. They come in all sizes and since a sub-avarage pilot like me crashes at almost every flight they are relatively cheap (about EUR 10 - 15)
