Just a simple question:
Are there any known 3D models (that can be 3D printed) for the chassis parts of the GoPiGo-3, particularly the bottom acrylic plate?
IMHO, a 3D printed bottom plate would be more rugged and less prone to cracking than the hard acrylic plastic plate that’s currently there.

I saw those and I thought they were like Gerber files used to manufacture the acrylic pieces.
So, which files do I need to 3D print something? (assuming I can get my grubby mitts on a 3D printer, 'eh?)

You can use the STL files - but you’ll need slicing software that can turn the STL file into gcode or another format the specific model of printer can use.

the STL files
Won’t he have to separate the various body parts into individual STL files (and get rid of the battery pack)?

I’m not swimming in this but could the “svg to stl converter ” convert the chassis file into the needed STL without having to separate out the desired parts?

But, as far as I can see, these are 2D models that could be used as cut-out templates for the laser cutters, but not for 3D printing.
That’s why I asked.
P.S.
If I’m going to print anything, I’d really like to print out the original servo mounts to use instead of the hideous “Lego” mounts we have now.

right, but they only need a thickness, which I think the svg-to-stl converter allows setting.
I really need to stop trying to feed cats more than they want. Gets me in trouble everytime.

Yeah. I hadn’t actually looked at the file - that’s what I get from assuming they were listed as individual parts.

Cool - didn’t know that existed. Seems like that would work.

I would like to propose a slant on this thread
Could we design a pair of new 3D printable plates to make a GoPiGo5 that would feature:
wider wheelbase for more accurate odometry (prob need longer motor/encoder cables)
room for mounting a Pi5 with cooler, to the GoPiGo3 board, and Battery on the bottom plate
room for a solid 5v 3A or perhaps even a 5A supply with a usb power delivery negotiated output
mount for MPU9250 IMU far away from every thing
