A set of printed components to build frameworks that incorporate servo and drive motors to build mechatronic / animatronic structures controlled by a Raspberry Pi.
Other related 3D print designs are here and here.
Detailed descriptions of all aspects of this evolving project are at this link and example ‘mechatronic’ software for a Raspberry Pi can be downloaded from here.
The various 3D prints developed for this project allow servo motors to be connected to 3.8mm (5/32 inch) diameter wooden dowels which, along with other dowel interconnects plus screw-down or Lego compatible stands, allow 2D/3D frameworks to be built.
Simple 2D animatronics can be built, as shown in the images, using cardboard cut-outs attached to the stand.
All the 3D print components use 1.75mm PLA and a layer height of 0.15mm with print details for each component produced on an i3 Mk3 shown in the table below.
