Drawing accessory for the XRP robotic kit

This is an accessory for the XRP robotics kit, that allows it to draw! Just easily attach a pen/marker and the robot becomes able to draw. I would not recommend you to use a pencil as it wears down with use.

It is pretty small (only 2.6cm wide), so you can combine it with different accessories for the robot. The sliding system is here because of the drawing - if you just put a rotating pencil holder, it would probably leave an unwanted mark on the paper.

First, I wanna thank Joe for providing the dimensions of a mounting bracket for the XRP robotics kit.

Printing recommendations:

Since I haven't a Prusa printer, I didn't test the sliced file from the Prusa slicer, so I'm sorry for any possible troubles.

• I didn't change the basic speed settings in the Bambu slicer and everything was okay so I think there's no need to change it.
• It will need some supports only on the upper side of the pen holder.

Assembly tutorial:

• First, mount a micro servo into the servo holder. It should fit perfectly. You can strengthen the servo using the screw included with the servo.

• Then, slide the pen/marker holder into the hole in the base.

• And attach a servo horn to the micro servo. You can use the smaller screw from the servo package to make it hold stronger.

• Finally, you can mount it to the XRP robotics kit's base.

Done!

I don't actually have the XRP robotics kit, so I created a simple replica for the photo :)

Good luck with 3D printing!
