SpoolScout

SpoolScout is a successful little project chugging along and making users happy. It’s a database for 3D printing filament, with the ability to find and compare them based on their physical, mechanical, and chemical properties.

I identified that there was a problem here - the different manufacturers don’t make it easy to find this data, but for many projects it’s quite critical.

I thought it’d be a fun project to throw an LLM at and see how far we could get. With an LLM alone, turns out, not that far. But with some tweaking, pretty far!

• Scrapes Amazon PAAPI5 for new prices every few hours with a Cron Worker
• I’ve built a sweet pipeline for ingesting and categorising new records. It’s all driven by an LLM under the hood.
• Spent time learning about SEO optimisation to try and pull in the right kind of traffic.
• I’ll write more about it soon!
