Dragonfly Science V2

I adjusted the print settings for printing with slic3r. BODY: I cut the body in 1/2, so no supports were needed. I made the eye hex and crank holes larger. First, clean up the body halves and front three crank holes using a 1/16" bit. Then glue the eye section together with crazy glue. Next, glue the tail section in place. Install the crank, gluing it near the crank holes and wing pivots, although this is not necessary. I formed the crank using a 1 mm paper clip and needle nose pliers. The offset was made with a 1/8" nozzle, and the journal was created with a 3/16" nozzle. The center offset is 1/4". File the wing pivots to about 2.8 mm in diameter. Since this model is not intended for flight, I used a second 1 mm paper clip for linkage and hand crank. Check the tail hole for fit-up and adjust as needed. You can use a #57 drill bit if necessary. WINGS: I relocated the pivot hole and made the legs larger for added strength. Slow down to 15-20% speed when printing near the wing legs. Use 10% infill, 3 shells with 3 layers of top and bottom solid, and one raft. Clean out the pivot hole using a 1/8" drill bit and the inside of the legs with a file. I used a timer to slow down the print speed to 15-20% three minutes before completion to avoid forgetting. The material above the wing pivot point is about 0.10 mm thick and fragile, so you'll need to make a new one if it breaks. LEGS: I modified the legs for this build. The body tail and crank section have a relief for easier leg fit, allowing them to slide into place smoothly. The plus leg will give a raked look when used as the back leg or cut from the front leg. Glue the legs in place once you achieve good balance if desired. Check out the full instructions on Thingiverse at http://www.thingiverse.com/thing:951687 for more details. Thinkpool did an excellent build job, and I'm looking forward to seeing their next creation. Please add your location to your profile; I'm always curious about where people are from.
