CubeCopter Mk1 (small - medium sized quadcopter)

thingiverse

Initially, I used a small printable quadcopter but faced issues with its arms constantly breaking and limited flight time. Being in Japan, space is restricted, so I decided to prioritize durability over mobility in my new design. The non-printable parts include a 60mm x 60mm x 5mm aluminum block, a 1m T-shaped aluminum rod cut into four equal lengths with dimensions of 15mm height and 13mm width, a double-sided velcro strap, and various m2 10 and 15mm bolts and nuts (obtained from Tokyu Hands). The motor blocks slide onto the rods and are designed as "full tang" with superglue for additional strength. For better flight control, I printed parts solid. The battery tray sits over electronics, while the multiwii flight controller is attached to the raised platform in the main compartment. GPS, radio, and battery alarm are placed on either side in sunken areas, secured with hot glue due to their lightweight. To ensure proper design, I avoid predrilled holes and plan for last-minute changes. Motor blocks accommodate a piece of wood between the motor and block to act as a heat buffer. The design includes support removal after printing, reducing plastic usage and print time by 25% and 10%, respectively.
