I bought a 3D printer

Welcome home, Bambulab A1 🤩 Bought the version with AMS because why not. 

Now... how the heck do I rewind the filament from a paper spool to a bambulab spool?

Edit: This is how. Cool!

Edit 2: What to do with filament poop?

Finally got the ESP32-CAM working

This was a headache. The RHYX M21-45 camera seems not to be compatible with the usual Arduino libraries and I had to do too much googling and trying advice from AI (to no avail, surprisingly). Finally I got it working by actually downgrading the AI Thinker ESP32-CAM library to some previous version (I think the 3.3.0 did not work).

It looks like a mess, but it works. I'll have to 3d print a nice enclosure and I'll probably use this as a very simple timelapse camera - I set it to take a picture every 30 minutes and send it my backend API endpoint.

Gridfinity is a godsend

For a long time, I was searching for a good system to organize storage spaces. Something that could neatly sort small-ish items, while still being flexible enough to adapt as my needs changed.

Then I discovered Gridfinity. I first came across it (probably on MakerWorld) while browsing for print models, and it instantly caught my attention. The concept is brilliant - modular, versatile, and packed with countless designs and layout options. Best of all, it can be rearranged or expanded at any time, making it future-proof. And if I ever need more, I can simply print additional base grids or components.

Also, it's very economic - each component only uses a few grams of filament, which means a single 1 kg spool can produce a huge number of them.
