Critical alarm: Electrical USB connections can harm to your computer. USB has low voltage, i worked with bare hands for electrical connections because i am Türk, but i advice to you work with nonconducting gloves.
Materials you need:
*Electrical motor (32mm diameter, 25mm height)
*USB cable (available from unserviceable mouse, keyboard, printer etc.)
*3D printing parts: 1 alt tabla, 1 gövde, 1 kafa, 1 kanat tutucu, 4 kanat, 1 motor kapağı)
Use ABS plastic.
Use acetone to combine parts. Nail polish removing acetone is useless, use technical acetone available from hardware store (called hırdavatçı in turkey). Apply acetone combining surface and press parts about 1,5-2 min.
USB socket has 4 cable. Keep USB socket terminal and cut the other end. Connect electrical motor cable and USB cable. Try 2 of 4 cables to connect electrical motor.
Combine 'kanat' with 'kanat tutucu' via acetone.
Fiil the space with residual materials in the 'kafa' before inserting the motor to 'kafa'. Get the motors cable from the hole under the 'kafa'. Combine 'motor kapağı' with 'kafa' to lock the motor.
Pass through the cable from gövde and connect the USB and motor cables choose before.
Combine 'gövde' and 'kafa'.
İnsert 'kanat tutucu' to 'motor'.
Connect USB to your computer and have fun.
Advanced note: To combining parts more strong, prepare paste with acetone and abs. Add acetone to a glass. Cut abs plastic small parts. Add small parts inside the acetone. After 15-20 min, ABS will be softener. Apply the softened ABS to combined parts interface. This treatment looks like welding.
