Human: Custom pan tilt mechanism with high-torque geared tilt platform & precision ball-raced pan rotation.\nAvailable at my website:https://www.3dprintcq.com/product-page/geared-pan-tilt\nFree Australian delivery on all orders, every time!\nUPDATE:\n .OBJ files have been added.\nThese updated files improve assembly quality & merge the two-part tilt axle into one file.\n Instructions This custom pan tilt was designed to serve as the base for my cutting-edge robot head (coming soon).\nThe goal was a stable platform with minimal play and superior strength in the tilt mechanism.\n6mm airsoft balls were used for bearings, but any 6mm ball can be used successfully. All the parts of the tilt mechanism are printed from one file. The servo base is designed to print separately. Printed orientation follows the format included in the files. A high-quality Up2 printer with fine layer height set at 0.15mm was utilized for the prints. Tilt pivot bearings measure MR106 (10 x 6 x 3mm). For the tilt servo, try this model: http://hobbyking.com/hobbyking/store/__45606__Corona_939MG_Digital_Metal_Gear_Servo_2_7kg_12_5g_0_13sec_AUS_Warehouse_.html For the pan servo, go with this option: http://hobbyking.com/hobbyking/store/__24578__Turnigy_TGY_4409MD_Metal_Gear_Digital_Servo_9_45kg_0_11sec_44g.html Assembling the top plate/tilt mechanism involves: Glueing servo mounts to top pan plate. The parts fit snugly, making acetone a suitable adhesive. Glue the mounting plate to the gear/shaft assembly while carefully aligning the holes and ensuring the mount aligns with the flat section of the gear on the opposite end of the shaft. The flat surface on which I aligned the shaft helps ensure accurate positioning. The mount was then glued into place using this technique. Press the bearings into the upright supports in an upright manner.\nPosition the gear/shaft assembly between the supports, carefully ensuring they are parallel. Place the mounting plate on top pan without glueing screws to the bottom upright first\nScrew the upper support onto the pan. Make sure it is at right angles & don't use longer screws that can bend bearing surfaces!
