so that’s my merch haul from @zoodotdev i don’t think anyone can top this

Ben’s Build Log #16 With KCL 3.0 released, I asked Zookeeper to migrate the entire project, review the existing code and make sure everything still worked as intended. With that done, I finished the propeller spacer, making use of the improved fillet capabilities in KCL 3.0 to smooth out the transitions around the mounting bolts and structural ribs.

A four-lobe helical supercharger rotor whose twisted profile moves air through the blower housing. Stepped bearing journals, seal lands, a drive keyway, and balance details integrate the support, sealing, and drive interfaces. Made with Zookeeper.

Ben’s Build Log #15 Moving on to the propeller, I asked Zookeeper to design a mounting plate that fits the existing crankshaft flange. I had him start with a sketch so I could review and validate the design before letting him turn it into the final 3D part.

Ben’s Build Log #14 With the rest of the engine components in place, I asked Zookeeper to create a functional linkage between the camshaft lobes and the valves. The first result already had the basic mechanism in place, but some of the geometry still needed refinement. After a few adjustments to make the setup cleaner and more realistic, the engine internals were finally complete.

A cutaway high-bypass turbofan exposing the engine architecture from the front fan through the compressor, combustor, turbine, shafts, nacelle, and exhaust. The layered modules make the gas path and supporting systems easy to inspect. Made with Zookeeper.

Ben’s Build Log #13 While reviewing the engine assembly, I realized there was a deeper logic issue in the way I had arranged the layout. After working through the problem with Zookeeper and exploring a few possible fixes, I reworked the affected geometry to better match the flat-four configuration typical for this kind of aircraft engine. The result is a more mechanically plausible setup that I’m much happier to continue with.

KCL 3 is a much saner language, from a PLT pov. Critically, this lays the ground for shipping opt-in breaking changes to KCL, like how Rust editions work. So we can improve our 3D topology algorithms, changing little details (like face/edge ordering) without breaking old models.

Zoo has released KCL 3! This release massively improves Zoo's fillets, and fixes a bunch of little papercuts in the KCL standard library and language semantics. Your KCL 2 files will still work fine, but new files will be created in KCL 3. Read more at zoo.dev/blog/kcl-3

Ben’s Build Log #12 An important part of the crankshaft and camshaft setup is the timing connection that keeps both shafts synchronized. In a four-stroke engine the camshaft rotates at half the crankshaft speed, so I had Zookeeper create a 2:1 gear setup between them.

A titanium acetabular implant cup concept with a hemispherical shell and liner-lock grooves defining the internal interface. Circumferential relief, radial features, and shallow exterior dimpling create a detailed bone-contact surface architecture. Made with Zookeeper.

One of the biggest questions we get about AI generated designs is "how does the AI know their performance?" The same way humans know, by running FEA. That's why @zoodotdev built FEA workflows into Zoo Design Studio, Zookeeper, and our APIs. You can set up and run these directly in Zoo Design studio, no exporting. Zookeeper can iterate on designs based on FEA results. Via our APIs, these FEA runs can be ran as a service for third party integrations, and by other agentic workflows. Been in beta internally, and by select enterprise customers, to be released broadly later this year.
