In a few days, I will stop using Twitter for project notifications. If you like to get notified about new projects and updates, please subscribe to the new mailing list:
It is a low-frequency mailing list, with one mail per new blog post and occasionally an update about a running project. I aim to keep the number of notification emails as low as possible.
You will never get advertisements, sponsoring or promotions, and you can unsubscribe anytime. If you think, you got advertisements or similar over this list, please contact me. I also recommend using a dedicated (throw-away) email address for mailing lists in general, so you have better control over who sends emails to you.

I've designed a simple magnetic filament filter that snaps onto a 16mm feed-through to catch dust and particles with a microfiber-wrapped sponge. It's easy to attach, low-friction, and printable in PETG — STL and Fusion360 files are included. Read the full post for printing, assembly and download links.
