First functional use of the new 3d printer:

Wife dropped her phone. Want to move its SIM into an old junk phone until we can get it repaired. Need a nano-to-micro SIM adapter. So we... downloaded one from the Internet for free?

I mean it is kindof obvious that's what one does with a 3d printer but the first time doing it feels awfully like we've got star trek replicators now.

btw, if it weren't for open source and especially copyleft enthusiasts totally driving the 3d printing movement from the beginning, we'd have none of this.

Instead it would be a glut of mutually-incompatible rent-seeking "model stores" crowing about how beneficent they are for "creating a marketplace" (in which they get a cut of all transactions)

It makes me so happy to see that nearly _all_ of the software and designs I have used for 3D printing so far is copyleft! 😍
