About this model

Always wanted a LEGO Grievous but didn't want to shell out to buy one used, so I made my own! I had to tinker a lot with the sizes to make them strong enough to not break but also fit with existing LEGO elements. This isn't perfect but I think I got reasonably close. The feet click on LEGO studs and while the arms are a bit loose for posing, they will grip eachother and LEGO lightsabers. If you want to tinker further, the arms are simple geometric shapes. The grippable parts of the arms and body are 3.2 mm wide. The hands are 5.2 mm wide with a 3.2 mm hole in the center and a 2.8 mm rectangular cutout on one side. I printed this with a .2 mm nozzle.
