OpenPanTilt is a RepRap-inspired 3D-printed Pan/Tilt head for timelapse photography with DSLR. It can carry your DSLR easily. Additional information can be found on my blog: http://diycrap.blogspot.no/2014/04/openpantilt-diy-3d-printed-pan-and-tilt.html Some details about the electronics can be found here: http://diycrap.blogspot.no/2015/05/openpantilt-electronics.html A video of OpenPanTilt in action: http://youtu.be/9RNaIifSeeY An example video produced by OpenPanTilt: http://youtu.be/bwUw9LBA-oE The OpenSCAD file is provided. Please edit and change the design to your taste. Have fun and hack the heck out of it.The unit consists of nine 3D-printed parts (the part numbers in the list correspond to those in the figure and to the individual files): 1: Camera mount with mounting holes for quick-release plate 2: Left part of the cradle 3: Right part of the cradle. The left and right parts are identical. 4: Tilt mount which holds the left part of the cradle and a NEMA17 stepper motor. 5: Right tilt mount 6: An upper pan mount which connects the two tilt mounts with M8 Rods and space for a lazy susan bearing. 7: Top cover for the pan stepper motor box, which also has a space for the second half of the lazy susan bearing. 8: The pan stepper motor box, containing the second NEMA17 motor. 9: The bottom cover of the pan stepper motor box. A quick release mount can be printed as a part of the cover as an option. The hardware pieces are as follows: 2x A-1Y-5MYK08RA Worm (from sdp-si) 2x A-1P-6MYK08R030 Worm Gear (from sdp-si) 2x NEMA17 stepper motor (The Pan engine should be max 40mm to fit inside part 8) 1x 25x42x11mm Axial Ball Thrust Bearing (a.k.a Lazy Susan bearing) (between part 6 and 7) 4x 8x16x5mm Axial Ball Thrust Bearing (on each side of part 4 and 5) 6x 5x12x4mm Bearing (2 each inside parts 4, 5 and 8) 60cm 8mm threaded rod, to connect parts 4,5,6 (length depends on the size of the camera) 60cm 6mm threaded rod, to connect parts 1,2,3 (length depends on the size of the camera) 20cm 5mm threaded rod, to connects parts 4,2 and 3,5 12 M8 nuts 12 M6 nuts 12 M8 locking washer 12 M6 locking washer 5 M5x75mm hex bolts, to assemble the parts 7,8 and 9, and one for connecting the pan motor to 6. 4 M5 nuts 4 M5 washers 8 M3x15mm screws (for motor mounts) 1 Camera Tripod Quick Release Plate 1.5x2 Inches, such as this one Some M5 washers to align the worm gears M2 bolt to secure the tilt axis to the M5 rod connected to the tilt stepper motor. There are many ways to assemble the unit. Below I describe my method: Start with cutting the M6 rods into two pieces. These two pieces connects the pars 1, 2 and 3 Make sure that the rods has sufficient length to ensure that your camera fits between 2 and 3, even with cables (such as power and remote control) attached. Then, assemble the cradle with M6 nuts and washers. The second step is to cut the M8 rods in adequate lengths and assemble the parts 4,6 and 5 with M8 nuts and washers. The third step is to mount the pan stepper motor and the gears into 8 and mount the lid (7) to the pan unit (6) with the axial thrust bearing in between. Voila, the OpenPanTilt is finished!
