3D printed quadrotor frame using Rotites


This is yet another version of a 3D printed quadrotor, pointed to be one of the workhorses of my research... The main characteristic of this frame is that instead of using nut and bolts to join the arms and the base together, like in TEGO v2, I'm using Rotite®s!!!!


For those who dont know what rotites are, you can give it a pick here, I was trying to find a solution to reduce weight of my previous TEGO v2 frame, and somehow I found this company, I immediately put in contact with them, and after several e-mail exchanges, phonecalls and even videoconferences with the inventor, I was able to get my hands on some of their designs, there is a picture below where Stuart is giving me a lecture about Rotites.


So, I started playing in Solidworks, and we did this design, usign 90 degrees A and B rotites, 4 B's on the main plate and one B on each arm.


The weight was dramatically reduced, and the endurance dramatically increased!!!

Many thanks to Stuart Burns (inventor of Rotite®) and of course, the Rotite® company to letting me use their designs :)

  • Yes, PLA

  • T3

    Is that PLA you're using?

  • It took me close to 3.5 hours of total printing (in several stages), I'm using a replicator 2... I have print tons, hehehe, i have several models flying in the labs :) 

    I'm looking to improve the design, I can find some things i need like a battery holder or so...

  • Hi, how many time to print all the frame and which printer are you using ? thank's !

  • I cant release, those are not mine, but put in contact with them on their site

  • T3

    Are the files something you can release?

  • That was my thoughts exactly... and then I printed a couple to test... and I was impressed!!! even if the printed quality is lower, the "lock" is even stronger... take a look at the video, and print a test!

    Very innovative connectors. A question : once rotated in place, how is the arm "locked"; I mean isn't there a risk that if the arm bumps something it would come loose ?
