For anyone who wants to contribute to individual FreeCAD contributors, there's now a Librapay team page set up.
It's my understanding that when you donate to the team, it gets evenly distributed among everyone in the team. You can still donate separately, and all three of the devs on there currently are also on Patreon.
Makerdon is a Mastodon instance focused on Makers, Open Source Hardware (OSHW) and STEM/STEAM. Free and Open Source Software (FOSS) is a likely topic as well. If you're interested in making things, allowing others to build on your work, and/or teaching others about making things, you might like this instance.
