3dp 12 inch flying ring v10

thingiverse

Human: 12 inch flying ring designed to fly far and true. Print Settings Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Rafts: No Supports: No Resolution: Low Infill: 50% Notes: The file has two ring segments out of the total of four required for the ring, so you will need to print two sessions to get the necessary parts. The prototype was initially printed using PLA and then printed with the PLA/PHA blend by PRINTinZ. The flying characteristics are the same but the PLA/PHA is better suited for surviving collisions. For the PLA/PHA filament I used a glass bed with hairspray and 40 C heating of the bed. The nozzle temp was 210 C and no slow-down in nozzle traverse speed was required. I increased the number of top solid layers from 2 to 3 to avoid tiny holes, but the tiny holes did not noticeably affect the ring's performance. Post-Printing Assembling and Flying Assembling the ring: The parts can be welded together using Plastruct Bondene solvent cement commonly found where model train supplies are sold. Put enough cement into two 8 ounce mason jars to submerge the joint areas. The solvent evaporates quickly and is potentially toxic so keep the jars tightly closed when not in use. Do this in a well-ventilated area. I set up a bench at the outside entrance to the garage with the door open. Using one jar, hold two ring segments top-to-top and put the joints in the solvent for 2 seconds. Quickly tap the excess solvent back into the jar and then on a flat, printer paper covered surface hold the joint together for 30 seconds. Peel the paper away from the joint area and put the welded part back on the paper for 30 minutes before further handling. Put something on each side of the joint to hold the ring segments flat on the table during the 30 minutes. Assemble the other ring half in the same way. When the ring halves are ready for further handling, put them top-to-top and using both mason jars, dip the four ends simultaneously for 2 seconds and quickly shake off the excess cement. Hold the ring halves together for 30 seconds, peel off the paper as before, and put the ring back on a dry part of the paper. Add weights to both sides of the new joints and allow the ring to cure another 30 minutes before handling again. I waited another 8 hours before flying the ring. Flying the Ring: The ring is easiest to fly with a vigorous throw into or sideways to any wind. I am right-handed, and my best and straightest throws were back-hand with a slight angle up and to the left. It tended to climb and turn slightly to the right at the beginning of the flight and, as it lost momentum, level and then drop off to the left. Of course, the relative wind direction has an effect on any turns during flight. The ring can go far so be careful!
