ceiling plane

thingiverse

Here is a plane that comes up to the ceiling with a cord and circles there. Please act with caution! You need: A ball bearing with the dimensions 8x3x3 mm is required. Or you can construct your own bracket with a ball bearing. It has to be a rotating bearing, otherwise the line will twist, causing it to stop and a wild backlash of the line. A motor that I removed from a nose hair trimmer - it's available from €3 / Diameter 20mm flat side 15mm, shaft with adapter or diameter 2mm. A battery type AA. A cable 15cm two-core. A cord about 50 cm. Printable without support. The motor is clicked in and holds without any further tools. There are 2 holes in the plane where the string is knotted to form a triangle. See picture. To launch the plane, rotate the bearing by hand (several turns) in the direction you want the plane to move (first clockwise). This is really only possible with the bearing, otherwise you will not be able to start. If the plane steers up or down, then change the direction of rotation and possibly break off parts of the rudder. Please act with caution! https://youtu.be/klw5-TAHXrc https://youtu.be/au-BLjA8Uqk
