I just completed a CAD model of the Cafelat Robot.

You are free to view it here:

Feel free to spin it around, change the colors, add the Barista style, move the levers up and down, spin the portafilter, hide parts, create cross sections, turn on the exploded views, change the display to lines only, etc. Grab a screen shot of your favorite view. Comment here if you have ideas or requests.

That's amazing! Your 2nd image (Blue) in your initial post, the Robot looks like an astronaut ready for a space walk.

Thanks for posting your wonderful creativity!

Looks good. My five suggestions to improve the Robot:

Rotate the pressure gauge 45 degrees (or more) until the face of the gauge can be seen from above when the user is pressing the arms, making espresso. Problem now is that one has to be bent over the machine to see the gauge, or be in an unnatural body-position to see the face of the gauge while pressing the Robots arms together.

Make the pressure gauge modular so one has the option to remove the stock gauge and custom install a T-split that allows for having both an analogue pressure gauge and a bluetooth pressure device, allowing for pressure profiling on the phone/tablet. As seen with the Flair-58.

Completely re-design the arms so they are easier on the hands to grip and press. I feel a huge feature about the Robot is how fast one can do repeated shots with it due to the fast workflow, not needing to pre-heat anything. So a more comfortable grip while pressing shots after shots is essential.

Wider base so that the legs can be spaced out a bit more so that normal-sized coffee weight-scales can be used on top of the base, between the legs. Problem now is the legs are too narrowly positioned, only allowing a few narrow-designed weight-scales to be used with the robot.

Improve the rubber o-ring surface-grip solution on the under-side of the base, so that it does not come loose so easily when moving the Robot around on a flat surface.

Amazing! Your LaPavoni models were also very useful.
In fact, they inspired me to also learn Onshape and I recently had some parts fabricated for my Strega, using a STEP file generated with Onhape. So thank you ;-)
