Ugh, not a fan of articles like this. Old hardware can continue to have plenty of uses, depending on what those uses are. (I was using a 2010 Mac Pro to run my laser cutter up until last year, and still have an even older iMac as a music player.)
I've been doing Arduino things for the past dozen years or so, and I was a huge supporter of the Arduino organization, and I still use the Arduino IDE, but I've mostly moved away from their boards in the past five years. I've used a lot of Teensy boards over the years (hundreds, actually) and the occasional UNO, Nano, and Micro, but the Raspberry Pi Pico has been my go-to board in the past few years, and I work in education where the micro:bit seems to really be taking off. It's a shame, because I'd love to see Arduino continue, but not as a closed-source company.
I've printed things that function as a block of wood with holes a number of times because believe it or not, it's sometimes easier. If I don't have the right scrap wood on hand, and the proper saw to cut it, sometimes printing is easier and safer. (For something like this where others may also need a replacement for an existing item, there's the extra bonus of sharing the model for others to benefit from.)
The design for this one was a digital drawing (though sometimes it's just analog/paper) and I then 3D printed a plate and did a relief print using a Provisional Press. (I'm also really into rainbow rolls lately!) I make my own paper and this is from a recent batch. (I recycle our shredded paper at home.) The frame is 3D printed and I designed that as well.
