Spherical Differential

Just to reiterate, this is an ongoing project. At some point, I'll add a drive shaft and so on. For now, though, I've simply given it a stand so you can spin the ring wheel by hand as much as you like :)\nThe photos are outdated, so take a look at the STL of the assembled parts for the latest view.\nI'm using four 3x10 screws to hold the frame together and one 3x20 screw to secure the two halves of the core.\nPrint Settings\nPrinter Brand:\n Ultimaker\n \n Printer:\n Ultimaker 2\n \n Rafts:\n Yes\n \n Supports:\n Yes\n \n Resolution:\n 0.4 nozzle __ 0.2 mm layer thickness\n \n Infill:\n 20%\n \n Notes:\n IMPORTANT!\nREAD THIS The bottom part of the gears is quite delicate as only the very tips of the teeth make contact with the build plate. For this reason, I've built a supplementary support structure directly into the STL file itself (see JPG). You'll still need slicer-generated supports for all other overhangs, though - use "touching build plate" instead of "everywhere". For the gears, I strongly recommend using a "brim" (single-layer thick raft, NOT a true raft).
