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.

  • Missing clip now available on 3DR' profile MMF here - https://www.myminifactory.com/object/iris-clip-20080

    many thanks again to Chris and 3DR fo sharing!

  • I think you need a printer that can handle at least 220mm.  You can't really scale anything since the holes or motors will not fit.

  • We printed all ours on Replicator 2 PLA Fillament. 

  • I use a kossel mini, but any PLA printer should be fine. 

  • What 3D printer do you all recommend for IRIS+ parts, I will not give up on my IRIS+ , Will be using it for business in a few months,,,

  • Here's the printed part:


    I write on my Blog here

    I am hoping to also print the canopy and fly a printed iris, I don't know if it will fit to my printer yet, but I will try. I also like the idea of making a 250/300 size iris, a 'mini iris' for auto missions in the park.

    It is nice to learn about the Iris+ design, and understand how this can be translated to 3D Printers. I'm having fun which makes me thankful for 3DR to release the files.

  • Hey, I already had some fun modifying the iris parts:

    I figured that I could use 16mm carbon tube, and slice the iris arm:

    here is the motor section

    @davidbuzz: I checked with the MyMiniFactory folks, and the DMCA complaint only concerned your use of their photos and walkthrough, not the actual design files themselves. So if you upload just the files with your own photos, not theirs, that should be fine. 

  • 3D Robotics

    @davidbuzz: Sigh. No idea what's going on there. Those are our files and they're free to distribute everywhere as long as the open source licence terms are maintained. I'll investigate. 

  • @Chris you rock! Thank you for keeping 3DR responsive to the community.
