After the crash of my inMoov robot it took a lot of work to put it back together. To prevent a crash again I decided buy a stable speaker stand for big speakers. To make it fit it was necessary to design a special block to connect the upper body of the inMoov robot to the 35 mm pipe of the speaker stand.
My speaker stand is from the brand Innox, but there are several brands offering the same product. For example: Speaker stand on Amazon.
You can find the STL file of this support on Thingiverse.com.
Make sure you take a look at the website from the designer of the inMoov robot at www.inmoov.fr.
