terminator style lower arm prosthetic

Human: T800 Style Lower Arm Prosthetic. The lower section is hollow, making it easy to fit onto a prosthetic arm socket. Scale the entire arm to the right size and adjust the finger parts accordingly. Next, heat up the T800 lower socket until it becomes moldable. Then, carefully push the T800 lower part into place within the prosthetic arm socket. Note that the prosthetic socket is not included in this model. Print Settings: Printer Brand: Deltaprintr Printer Model: Deltaprintr Kit Rafting: Doesn't Matter Supports: No Notes: I printed this in PETG with a 0.6 nozzle and achieved a layer height of 0.4 mm without any issues. The middle section of the arm produced a non-manifold, but Slic3r handled it seamlessly. Post-Printing: Fitting the T800 Style Arm to the Prosthetic Socket The lower part of the T800 style arm is hollow and can be made moldable by heating it up. Simply place this onto the prosthetic socket and ensure proper alignment. After cooling down, connect these parts using glue or a mechanical fixture. To add extra flexibility to the fingers, I attached coil springs that allow them to extend after flexion. The lower and mid sections are bolted together with a rubber spacer in between for smooth rotation. Secure the bolt properly by gluing it in place. For added convenience, you can print this model with the mid part on top of the lower part, but keep in mind that this limits arm movement. I also incorporated filaflex into the fingers, enabling them to flex when pulled. To further improve this design, I plan to redraw the finger tips so bolts are no longer needed to secure the filaflex.
