alt Hacker NewsCommercializing doesn't really make sense. So I need to get a small 1x1x3 container to store washers or whatever. With my 3D printer, I'll have that container in under an hour. Even if I bought it with the fastest shipping Amazon has available, assuming it was from a local Warehouse, the earliest I could get it would be half a day away. Having a local store that sells them would be marginally faster, but then I have to go to the store, pick it up and come home. The hour I spend waiting for the printer isn't an hour. I'm I'm completely blocked from doing anything else. It's just an hour in which my printers busy.
The example you bring up is for a single one-off extension. Yeah, for that case it doesn't make a lot of sense.
However, for initial setup of the system (e.g. filling up multiple drawers with baseplates and basic bins, as you will see in many videos online), it would definitely jump start the process a lot, where you'll otherwise spend weeks printing everything. Additionally, if you also go for the fancier baseplates/bins that include the magnets you'll also spend quite a bit of time on assembly and will require external hardware anyways.
I personally didn't think it was a big deal as for me adopting the system incrementally over time worked quite well, but I think there definitely is a niche of people (and possibly businesses) that would like to adopt Gridfinity for its other benefits and appreciate faster initial setup time.
