Here is a marker holder that can attach to the XRP to help with path tracing, etc…

Thanks for sharing!  
Did you try the built-in marker holder located directly behind the usb connector? It’s aligned with the line connecting the motor axles.

Yes, but this allows for a bit more visualization of the arc paths, especially when looking at the inside vs outside of the arc. we should put marker holders everywhere 🙂

Like a [Spirograph](https://en.wikipedia.org/wiki/Spirograph)?

I have another option for a marker holder that attaches to the Servo arm that I designed. It is a very short print out of TPU. I did a writeup on it on [Maker.io](http://Maker.io) if you would like to check out [Fusion 360 Design for 3D-Printed Marker Holder for XRP Robot (digikey.com)](https://www.digikey.com/en/maker/projects/creating-a-maker-holder-for-the-xrp-in-fusion-360/bd771f287ed6497fa1d2637e31a6962e)

edit: I just realized the Thingiverse link isn’t working at the moment. I’ll get that updated and post once its live.

edit 2: Thingiverse link is now working.

@TFossDK  
Thanks for sharing this alternative marker holder. A lot of drawing depends on lifting the pen so it’s great to have this option.  
I especially appreciate the fact that you included the .step file for other users to remix. That’s essential for a fully open source project.  
I also appreciate the brief Fusion 360 tutorial that you included in your write-up. I helps others to see how they can begin their own designs.
