About this model

This is the third, and last, file publish of my robotic arm series. This component is the arm of the robotic arm. The following hardware will be needed to assemble the arm: - M3 x 8mm round head(22x), 20 used to mount the servo horns (including the gripper) - M3 x 10mm round head(34x) - M3 x 63mm round head (2x) - M3 x 16mm round head (4x) - M3 nut (2x) - M4 x 16mm round head(4x) - 8mm x 16mm x 5mm bearing, 688zz (2x) The following electronic parts will be needed: - Standard size servo (5x), e.g. TowerPro MG995 The assembly should be pretty straight forward, just follow the exploded view. Questions?? Message me! Notes: - Print the base servo mount, bearing holder, center arm bearing guide, center arm bearing guide clamp and the lower arm bushing twice. - All critical holes are oversized by…
