Upgraded helicopter toy blades

thingiverse

I made several sets of scooped blades for this toy using my design, which worked perfectly when used in other similar toys. Printed with two walls and zero infill, they are remarkably lightweight and fly smoothly. A slight flat angle at the top of each blade is a minor issue, but it didn't pose any problems during printing as long as I kept supports to a minimum. To ensure proper adhesion along the outer rim, I always use a raft when printing props like these.
