That can make identifying one a real pain, but good news! Cue the nerdiest thing we’ve ever posted (ok, since this at least) – PIQABRICK!
PIQABRICK is effectively a 3D scanner that can identify any LEGO piece, even the oddities above, revealing the part code that can be dropped into third-party brick marketplaces such as BrickOwl and Bricklink.
Now obviously you have to own the piece that you want to identify already, but for those more seriously into the art of LEGO model making, or the few that do it professionally, PIQABRICK could save hours of research.
Take a look at the video below see how it works, and click here to follow the project in advance of its launch on Kickstarter.
