<p>This is a 3D printable prosthetic foot with the connector to pylon used on conventional prosthetics. It has the ankle joint and flexible fingers to achieve better walking dynamics.</p><p>The design was made in Autodesk Fusion 360 and was printed in more than 4 iterations before we have achieved the right fit, function and strength.</p><p><strong>PRINT INSTRUCTIONS:</strong></p><p><strong>All printed with Original Prusa i3 MK3S, with 0.4mm nozzle</strong></p><p><strong>BOTTOM FOOT: </strong>Filament:<strong> </strong>FlexFill98A, Layer Height: 0.3mm, Infill:<strong> </strong>20-40%, Fill Pattern:<strong> </strong>Adaptive Cubic, Perimeters:<strong> &nbsp;</strong>4, It is recommended to increase number of bottom solid layers.&nbsp;</p><p><strong>UPPER FOOT: </strong>Filament:<strong> </strong>PET-G, Layer Height: 0.3mm, Infill:<strong> </strong>40-100% (areas under heavy load 100% other areas 40%), Perimeters:<strong> &nbsp;</strong>4</p><p><strong>FLEX CUBE:</strong> Filament: Filaflex40, Infill: 40% (depending on the weight of the person), Layer height: 0.2</p><p><strong>SIDE JOINTS: &nbsp;</strong>Filament:<strong> </strong>PET-G, Infill:<strong> </strong>100%, Perimeters:<strong> &nbsp;</strong>3, layer height: 0.2</p><p><strong>TOP JOINT: </strong>Filament:<strong> </strong>PET-G, Infill:<strong> </strong>100%, Perimeters:<strong> &nbsp;</strong>5, layer height: 0.2</p><p><strong>BOTTOM RUBBER: </strong>Filament: FilaFlexible 40</p><p><strong>Additional material:</strong></p><ol><li>3 bolts, nuts and washers for attaching the bottom foot</li><li>1 bolt and nut and 4 washer of size for the joint</li><li>1 bolt and nut for attaching the side joints</li><li>1 metal cylinder diameter 10mm, length 20mm</li><li>Strong spring - depending on the weight of the person</li></ol><p><strong>All parts needs to be customized for the particular beneficiary.</strong></p><p><strong>ASSEMBLING:</strong></p><ol><li>Insert the washer in the holes found on Bottom foot followed by the bolts.</li><li>Insert the nuts in the holes found on the Top foot.</li><li>Tighten the bolt using a spanner(L type spanner works great)</li><li>Glue the side joints on the top foot, and use size 10 bolt and nut to tighten them</li><li>Insert the Flex Cube in the top foot</li><li>Pour glue in the hole found on the top part part of the foot and Insert a metal cylinder (stainless steel is preferred) in the hole.</li><li>Insert the spring between the foot and top joint in between the pins and add washers between the spring and 3D printed parts (we recommend to glue the washers).</li><li>Insert the joint on the foot.</li><li>Attach a washer between and after the side joints , and insert the bolt.</li><li>Tighten a bolt and nut slightly.
