About this model

A you tube build video will be added soon. This 3d printable Robby the Robot heart box can be built fully working or static for cosplay. The main frame is 232mm by 139mm by 50mm tall. So you need a large 3d printer like a CR10S5 or you can print the main frame in 2 parts. STL files for both are provided. I used TT 48:1 gear motors as they are easy to find these days, but you might want to source the 120:1 TT gear motors. They have more power and run slower so less noise. And you can power them up to 6 volts if you want the speed back. The build video will tell you all about the options.
