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.

That is really good news. I want give a try.

Original files at MyMiniFactory require registration before you can download them.   If you don't want to do that, I've made them also available here:

"Design files for IRIS+ now open source"

I wonder what's the relation between "open source" and releasing STL files :)

it does not look like the design has really been made open source so that we can play with, looks a bit more of source-less binary blobs to me.

The IRIS+ will live forever through Thingiverse now.

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

Awesome news!

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!

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.

Comment by Randy on March 15, 2016 at 8:21pm

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.

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.
