THE CROP DUSTER- BY AMEENINGFUL DESIGNhttps://youtube.com/shorts/g0HjAFrH5pc THIS PLANE IS A FULLY PRINTABLE SEED SPREADER THAT MAKES PLANTING A GARDEN FUNTHE PLANE UTILIZES A LEAD SCREW THAT, ONCE LAUNCHED, USES THE AIR RESISTANCE AGAINST THE PROPELLER TO SPREAD SEEDS OVER THE AREA IT FLYS. BEST FOR USE WITH UNIFORM SMALL SEEDS WITH A SIZE OF 1/16" OR SMALLER.INSTRUCTIONS TO FLY:1: ASSEMBLE AS SHOWN IN EXPLOSION PICTURE ON TABLE OR SURFACE OF CHOICE. THE INCLUDED BRACKET WORKS WITH TABLES LESS THEN 2.25" (OPTION TO SHOOT WITHOUT SURFACE IF NON IS ALSO INCLUDED BUT FLIGHT PATH IS LESS PREDICTABLE).2: FILL HOPPER AT BACK OF PLANE WITH SEEDS OF CHOICE.3: COVER HOPPER WITH CAP.4: LOAD PLANE ONTO LAUNCH CARRIAGE AND FULLY SEAT SCREW IN ANTI ROTATE FEATURE ON THE CARRAIGE (WARNING, FAILURE TO FULLY SEAT MAY ALLOW FOR COLLISION WITH ITEMS WHEN BEING LAUNCHED).5: CONNECT CARRIAGE TO RUBBER BANDS AND PULL BACK.6: RELEASE CARRIAGE AND ENJOY YOUR NEWLY PLANTED GARDEN.IT MIGHT BE USEFUL TO DO A FEW TRIAL RUNS TO LEARN THE ARC OF THE PLANE BEFORE LOADING IT WITH SEEDS.NOTES ON PRINTING, I PRINTED MOST ITEMS OUT OF PETG BECAUSE IT TENDS TO BE  A LITTLE MORE FLEXIBLE. THE DAMPERS WERE PRINTED OUT OF TPU TO PREVENT SHOCK LOADING THE TOP ASSEMBLY WHEN LAUNCHING (MIGHT WORK IN PETG AS WELL). I PRINTED THE PLANE AND SCREW TOGETHER IN PLACE TO PROVIDE SUPPORT AS YOU GET TO THE TOP OF THE SCREW. A WELL TUNED PRINTER HELPS HERE AS THE TOLERENCES ARE PRETTY TIGHT TO PREVENT THE SEEDS FROM JAMMING. IF THE SHAFT DOESN'T SPIN FREELY, A LITTLE SANDING GOES ALONG WAY.ITEMS TO PRINTCROP DUSTER AND SCREW QTY 1DAMPER QTY 2DOWEL SPANNER QTY 2HOPPER TOP QTY 1LARGE SCREW QTY 2LAUNCH CARRAIGE QTY 1PRINT IN PLACE TABLE MOUNT QTY 2PROP TO SHAFT CONNECTION QTY 2RUBBER BAND MOUNT QTY 1SMALL SCREW QTY 2TOROIDAL PROPELLER QTY 1 OTHER ITEMS3/8" DOWEL RODS QTY 21/8" X 7 RUBBER BANDS QTY X2-6NOTE FROM THE DESIGNER: THIS WAS DESIGNED SPECIFICALLY FOR THE PRINTABLES.COM MAKE IT FLY COMPETITION AND I WANTED TO DESIGN SOMETHING UNIQUE THAT SERVED A PURPOSE.
