What kind of mask, preferably with changeable filters, should I wear when working with plastic? Cutting, heating and glueing it. And 3d printing.
Something I can buy at a hardware store (or similar)

I'm getting overwhelmed with information when I try looking it up

Are you into 3D printing, self-hosting and the Fediverse?

If so you might want to look into Manyfold, a FOSS Fediverse platform which lets you upload and share 3D print models:

🌱 https://manyfold.app

You can follow the official accounts at:

🌱 @manyfold@3dp.chat (main)
🌱 @manyfold@makertube.net (videos)

You can host your own Manyfold server using the instructions at https://manyfold.app/get-started/installation (be warned though, installation does require a bit of tech skill).

We Can Still Stop California's 3D Printer Surveillance Scheme

California’s attack on 3D printing is heading to the Senate. Here’s how it has changed, and why we still oppose it. https://www.eff.org/deeplinks/2026/06/we-can-still-stop-californias-3d-printer-surveillance-scheme #privacy #opensource #3dprinting

Own a 3D printer?
The fediverse has a platform for that!

You can explore 3D prints that can send g-code directly to your printer.

(Follow @manyfold and @floppy and spread the word, the fediverse thrives via boosts and spreading awareness to other projects)

New York & California now require 3D printers to "block" gun files.

Problem: a printer can't tell a gun part from a pipe fitting.

Open-source firmware can't be locked down either.

It's not pretty, but this mash up works! The Nvidia Tesla V100 was toasty with the 17mm fan, so put in a 33mm fan. Louder in my office (fine going to basement.) But it's 82F/28C and now it's keeping the GPU MUCH cooler.

Updates on the quadruped robot: https://writerofminds.blogspot.com/2026/06/ace-quadruped-2026.html I am about ready for final assembly and a proper test of the new motors, though that will have to wait until <gestures vaguely>.

Anyone here using RepRapFirmware on their cnc mill (or 3D printer)? I have some questions related to planning out my controls cabinet.

Specifically I want to know if there is a way I can tie a button or switch in for motion enable/disable and use a contactor to cut power to the drives/spindle

I’m also assuming I can have standard start/hold push buttons. I am used to having my fingers on buttons to pause and resume without taking my eyes off the work…

California AB 2047: The End of Open Source 3D Printing

California just introduced a bill that doesn't just regulate "ghost guns", it mandates a digital kill switch for every 3D printer sold. California AB 2047 requires "blocking technology" that connects your printer to a government-approved database before every single print. If the system goes down, or your file is flagged, your hardware becomes a paperweight.

This isn't just about firearms. This is the death of Open Source. If this bill passes, it effectively bans Marlin, Klipper, and Orca Slicer, forcing every manufacturer to lock down their firmware. It turns general-purpose computing into a walled garden where you only rent permission to use the hardware you own.
