Prints on the Bambu P1S in exactly 30 minutes with the provided 3mf file. Print in PLA with 100% infill. Be careful not to bend the wings while removing from the build plate.

Instructions:

-

Once you take the glider off the build plate, flip it over(flat side facing up) and fold the two elevators up as shown above. Fold between 30 to 45 degrees, it is better to fold lower than higher.

-

Next, fold up the 2 stabilizers exactly 90 degrees. Make sure that the weighted side of the head is facing down relative to the stabilizers and elevators.

The glider should look similar to the image shown. To throw, hold between the wings and head of the plane. Throw it like a dart, but with less force. If the glider flies to the left or right, make sure that the stabilizers are at a 90 degree angle or manually adjust the flaps on the stabilizers. If the glider doesn't stay at the same height, lower or raise the elevators until it does consistently.
