Customizable Transformer / Action Figure Swivel Joint Replacement

thingiverse

If you can print with TPU, I highly recommend using that material. It's incredibly tough and will likely be stronger than the original, yet it will still work seamlessly with PLA. The T-shapes protruding from the cones are built into supports that need to be trimmed away after printing. The model is designed to be printed with the ends of these T-supports on the print bed. This orientation will strengthen the swivel joint by having the filament run axially, rather than creating rings. Additionally, there's a "cooling tower" model included, allowing layers to cool since the part is relatively small.
