DELTA PIPE PRINTER (DPP) Please refer to the DELTA PIPE PRINTER STEP 1 TOP FRAME for additional references and instructions http://www.thingiverse.com/thing:1344167 The good thing about this design so far is that the stepper motor floats above the desk, providing better ventilation. UPDATE 2016-12-23: I've updated the photo with my new color (the other images are for a friend). UPDATE 2016-12-13: I completed printing my 3 motor mounts and finalized the instructions. UPDATE 2016-12-11: I revised the MOTOR MOUNT STL again, this version is better suited for printers like mine. UPDATE 2016-12-10: I updated the MOTOR MOUNT STL; after testing it, I made some adjustments. The new file is improved, and I'll test it tomorrow... Custom Section MAKING HOLES On each of the CORNER SECTION from the BOTTOM FRAME, you need to make holes for the motor. You should drill a hole about 1 1/8" or 1 1/4" on the outside; this will be used for maintenance as well as the IDLER END SENSOR will exit through this hole. (PIC 1) The other hole is where the motor pole/gear goes in and out. This requires a slightly larger diameter than the gear to allow it to move freely. (PIC2) PIC1 Make an opening large enough for the gear to enter... PIC2 PRINTING MOTOR MOUNT Use the motor mount STL from this thing. The SCAD file will be updated on the STEP 1 in a zip. I printed this motor mount with 20 infill density. Print three motor mounts when done. Next, take each motor mount and drill two 5/64" holes in the ABS where the smaller hole was previously made. Note that these small holes must be smaller than the M3 screws. Once drilled, use a tool to create threads on the holes so the screws can screw directly into the ABS. Before making the holes, ensure the motor mount is centered on the middle pipe section. Tool I used to make thread on a pipe for testing... ASSEMBLING MOTOR MOUNT Total screws needed: M3 - 8mm X 9 M3 - 12 or 16mm X 6 M3 washers X 15 You need three 8 mm M3 screws to secure the motor into the motor mount with washers. You need two 12 or 16 mm M3 screws to attach the motor mount to the ABS Tee with washers. Use 16 mm if you're using lock nuts. Do this process three times. Motor installed on the motor mount! Install the gear first, ensuring it's flush with the plastic extremity like in this image. Center the gear before making holes and double-check your work. You should place two M3 16mm screws with washers... The motor is securely attached to the ABS, solid as a rock.
