Design files for IRIS+ now open source


Good news for IRIS+ fans. We've released the CAD files as STLs, so you can 3D print any replacement parts you need for free, including improved versions of the legs that are 50% lighter and require less support when printing. 


Our friends at MyMiniFactory are hosting these and have prepared a great tutorial on how to use them:

3D Robotics have been strong adovcates of open source collaboration and their IRIS+ and MADE FOR SOLO projects are testimony to that. 

If that wasn't enough, in all their awesomeness they have decided to give back to the community by giving away the files for the IRIS+ for free!

Over the last week MyMiniFactory has been building the first ever 3D printed IRIS+, so as to document the process and highlight any issues along the way.

In light of this Kirby Downey has released an optimised version of the arms and legs which are up to 50% lighter and require less support - download here.


Follows MyMiniFactory's step by step guide:


1) Remove the bottom shell by taking out the screws

2) On this shell, remove the LED and USB devices and insert them on the 3D printed bottom shell

3) Remove the screws that hold the bottom plate, and remove the top shell

4) On the top shell, disconnect all the wires from the pixhawk remember the way they were connected and where they were going

5) Take out the pixhawk and all the components that are are glued or screwed to the plate and place them on the 3D printed top plate

6) On the bottom plate, remove the connections to the pixhawk and remove the screws that hold the arms of the drone

7) Remove the foam carefully from the bottom plate

8) Take out the screws that holds the board and put it back the 3D printed small plate

9) Remove the 3 clips that holds the wires in the center of the arm

10) Close to the motor, make two marks on each wire so you don’t mix them once they are cut.

11) Cut the wires, take out the 2 screws that hold the motor and insert it into the 3D printed arm.

12) Solder the wires (you can use heat shrink wire wrap to hold your soldered joint) and put the clips back.

13) Screw the arms to the plate and the shell

14) Take out all the components that are glued to the top shell and place them into the 3D printed shell

15) Glue the foam of top plate back on the small plate.

16) Connect all the wires to the pixhawk again.

17) Screw the 3D printed top shell and the piece for the gimbal at the bottom.

  • Hey, where's those nasty clips you don't sell.  I already 3D printed some from my own design and they work great.

  • Thanks for this Chris. I wanted to ask, now that you've stopped selling the Quad Frame kit, please can you also upload the design files for that too? I'd really like the option of laser cutting or printing a new frame if I have a bad crash. I'd hate to rebuild my drone once again to ensure I have spare parts.

    Thx Chris for that!

  • If there is original 3D CAD file, we could make our own modification on this Iris+ and share them.

  • What's a good source of threaded insert for the standard Iris+ machine screws? I mean, it's one thing to be able to print the arms, but you still have to be able to screw everything together.

    Hats off to you Chris!  Very nicely done.

    The 3D printed parts may not be as strong as the originals but whatever, this is great news.

  • PS.  Thank you Chris Anderson for releasing these files.....I'm very excited to experiment with the lighter version to compare flight times and strength. We should learn a lot from this.

  • Absolutely fantastic. This will be a great resource for my students. 

    We have been working hard at fundraising and  purchased an Iris, a few spare iris motors, spare legs, and a Black Pearl monitor. We also have a  MakerBot replicator from and earlier fundraiser campaign. 

    We are currently printing prop guards for the Iris and a small servo module that snaps onto the iris arm.

    We are using the Iris to drop eggs in the ultimate egg drop activity from various heights. We attached a Hitec55 servo to the arm of the Iris and use it to release the egg container that is supposed to protect the egg from breaking. That is a new spin on an old physics activity!

    A GoPro films the action from above and viewed from below on the monitor. The students love using the Iris for various activities.

    Cant' wait to start printing a new Iris. Hopefully next year we will get the electronics to have another Iris! 

    Wish us Luck!

    Awesome news!

  • Though it took lot of time to make the IRIS+ design files open source but still quite good for the RC DIY community
