This model is 462mm wide.

If you have the complete set of Wera 3/8" sockets AND a printer that can print 462mm in one go, please don't talk to me :) Otherwise, please see SLTs split in 2 and 3 parts.

Picures by @dtsn in the comments, thank you!

Assembly: I split the model along the grid, so things should snap into place and align just fine. But I guess you can also glue it :)
