It's funny how many people have redesigned Gridfinity. This looks like a solid improvement in a few areas. If you make it, let us know how it goes.

The 4040 adapters ought to have magnets, though, IMO.

I use a Prusa MK3 (not MK3S/+) that I got in 2018. Later this year I hope to get an MK4 to join it, and maybe a Voron 2.4 for big prints. My first printer was a SeeMeCNC Rostock MAX from 2013. Its controller board died for the second time just before I got the MK3, and I never fixed it.

Merci Argonaute! 😝

I use my printer as part of larger projects. Furniture gets new legs. Kitchen gets new spice rack. Appliances get small repairs or mods. TV gets soundbar attached. Desk gets hook for headphones. That kind of stuff. It's all one-of-a-kind and of no use to anybody else, but extremely satisfying to model, print, and use.

(I had a bunch of photos on Twitter. Can't link now, might copy to the Fediverse later.)

I need to make one of these for my Scarlett 2i2. I like your design.

We usually start big purchases like that by reading The Wirecutter. We don't always buy what they recommend, but they'll suggest some criteria that we may or may not feel are important and review a number of products. When the Internet is a swamp of reviews-for-pay and SEO non-reviews, Wirecutter has the advantage that they actually evaluate products.

As for vacuums, we bought a Dyson V15 a few months ago. It's big, which makes it inconvenient both to operate and to store, but it sucks mightily (in a good way). We haven't used the plug-in canister vacuum at all for a couple of years now.

Our older Dyson, a V6, has new batteries and has recently been cleaned, and is relegated to bedroom cleaning. It doesn't suck nearly as well.
