Carburador de Fusca Brosol Solex 32 VW Beetle Carburetor

I'm super excited to share with you a really cool project I've been working on - a 3D printed carburetor for my VW Beetle! You can find me on Instagram @scalla3d. Recently, there was a huge buzz online about a Brazilian engineer who created a functional carburator using an SLA printer. I wanted to pay homage to that innovation by sharing the 3D model of my own carburetor project with you all! This particular carburetor is used in all VW models with dual carburation, and it was designed by taking apart a genuine Solex H32/34 carburator and studying its components. The goal was to see if I could create a working carburator using just plastic and an FDM printer. The design includes all the main components needed for assembly, but some additional parts will be required from a hardware store or junkyard. I recommend using the original butterfly shaft, diaphragm, gasket, and injector tube. One of the key challenges was finding materials that could withstand both high temperatures and corrosive fuel. After experimenting with different plastics, I found that PETG provided excellent stability for a short period but eventually began to crack due to gasolene exposure. PLA showed promise but melted easily under heat, while ABS simply couldn't handle the fuel's chemical attack. As you can see from my results so far, finding the perfect material has been an ongoing challenge. I'd love to get your input and suggestions on how to improve this design! Feel free to share any insights or advancements in the comments below!
