For the valve mechanism, I needed to add compression springs, but wasn’t sure about the best way to model them in Zoo Design Studio.
So I asked Zookeeper which approach he would recommend. He suggested using a helix, which turned out to be exactly what I needed for the spring geometry.

A floor-mounted racing brake pedal with a sculpted billet lever and deep weight-relief pockets. Connected diagonal ribs stiffen the load path, while the concave traction pad and heel lip support consistent foot placement. Made with Zookeeper.

A forged V8 connecting rod with a reinforced big end, compact wrist-pin boss, and tapered I-beam shank carrying load between them. Chamfered bosses and oil-relief details support assembly and lubrication. Made with Zookeeper.

After modeling the crankshaft and pistons, I asked Zookeeper to bring everything together.
Instead of positioning every part myself, he took over and assembled the almost complete engine internals.

I like AI that does not just make nice images but stuff that actually works. Below is the thread of me using traditional cad flow and using ai as a teacher for the little diy project. 🧵 1/7

Before finishing the wings, I wanted to start on the aircraft’s piston engine, beginning with the crankshaft.
I noticed I had gotten the propeller mounting flange slightly wrong, so I gave Zookeeper reference images of a real aircraft crankshaft.
Zookeeper corrected the geometry and laid the groundwork for the rest of the crankshaft.

A machined clevis bracket with paired lugs and coaxial pivot bores defining the linkage interface. Integral gussets transfer load into the mounting base, while the clevis gap and relieved lug faces provide assembly clearance. Made with Zookeeper.

A wing obviously has more than just one rib, so I let Zookeeper duplicate the rib along the entire wingspan.
Then I had him extend the spars and stringers through all the ribs to complete the internal wing structure.

i jumped out of a plane last weekend
and actually, it was a cessna 172, which is also the aircraft i use as a reference for my modelling work at @zoodotdev
insane experience though, definitely need to do that again sometime

To model the aircraft wing, I first needed to define the rib and its spar geometry.
I sketched out the rough profiles I wanted by hand and gave them to Zookeeper to size them properly.

A spacecraft reaction-wheel rotor with a stepped outer rim that concentrates rotational inertia and six curved spokes carrying load to the hub. Bearing seats, the central bore, relief grooves, and balancing dimples support alignment and mass tuning. Made with Zookeeper.

I was modeling the fork and oleo strut of the nose landing gear when I wondered if Zookeeper could take over from there.
It completed the assembly and even suggested the next steps.

A hollow-forged bicycle crank arm with a continuous load path between the spindle and pedal bosses. Sculpted front and rear relief pockets reduce mass while retaining material around the primary interfaces. Made with Zookeeper.

For the wheel rims, I needed some info on how the bolt assembly is typically constructed on aircraft wheels.
I asked Zookeeper for some technical context and it gave me a breakdown and technical drawings to support my modelling.

🏆 API Makeathon Winners Announcement 🏆
You all seriously raised the bar with this API Makeathon. The submissions were inventive, technically impressive, and full of ideas we didn't see coming.
A huge thank you to everyone who built and submitted a project! There was no shortage of standout work, which made choosing just a few winners incredibly tough.
With that said… let’s meet the winners. 🧵

🌟 Team Pick: BeaverFlow @shawnlkiser - github.com/slkiser/beaverflo…
Nodes! Flow-based programming is a natural fit for mapping processes visually, and that's what slkiser did here. BeaverFlow lets you define many inputs that feed into intermediate steps and processes, eventually generating useful output. What a great way to bring many tools together!
