Devlog #3: designed and printed the entire drone chassis

big hardware milestone today, i designed and 3d printed the entire drone chassis.

did the whole design in onshape. spent a good while on the layout because the chassis has to hold everything: the flight controller, the ESC, the motor arms, the battery, the raspberry pi, and the gps/compass. i measured each component so i could put proper mounting holes and slots for all of them instead of just taping stuff to a plate. the motor arm spacing and overall geometry took the most back and forth, it has to be symmetric and square or the drone won’t fly right. M

after a few tweaks to the model i sent it to the printer.

next up is mounting everything onto it and starting the wiring.

Hi Zach! This video on youtube is not too technical but it gives you a good idea on how drones work and what components are needed https://www.youtube.com/watch?v=qNTv5SgM0BM.

@rishe

printing the entire chassis in one go is commitment -what material? PLA or going PETG for outdoor durability?

@rishithc

I mean, I used CF tubes for the legs. But for the main central part of the drone that houses the electronics I used PLA then treated it with resin and epoxy.
