Pasco Smart Cart Base

I wanted a way to investigate the friction of different surfaces using a Pasco smart cart as the force sensor.

This is what I came up with.
The bases stack.
One base gives a PLA surface, another a felt surface and the last a cork surface.
You could have other surfaces just by gluing some material to a base using contact cement.

I got the felt at a Michael's craft store.
The cork is about 1.5mm thick with an adhesive back that I bought at a home supplies store.

Attach the hook to your Pasco cart, a string to the hook then record force and pull the string to get a graph of each material.

### Print settings
Nothing special.
I used PLA at 0.2mm layer height.


I was going to export the file as a STL too but Fusion 360 decided to force me to upgrade today and I have to rush home. I'll export it later and upload it. You can use the 3mf file in a lot of slicers as just like a STL file.
