BlimpDuino 2 is a very low cost open source autonomous blimp. It consists of an Arduino-based blimp controller board with on-board WIFI and laser sensors. Two vectoring differential thrusters and one lifting propeller.
Simple but exciting ;-)

The gondola has been designed to be sturdy and light at the same time and do not vibrate even when the motors are delivering their maximum power. If you are printing the gondola and arms by yourself , set a printing infill of 10% and walls thickness to 0.8mm.
Increasing the infill will not improve the sturdiness of the frame but will drastically increase the total weight. As the wings have been created as different parts, you can use different colors for them. Print it slowly trying to avoid stringing.
If your parts are curling in the print, you can try including a brim or a raft. PLA or PETG filaments do the job perfectly.
Once the different parts have been printed, remove them gently from the heatbed and clean them up using a knife. Keep in mind that the frame is fragile.
