Tutorial Build PackCredit to Space Guy for the inverted corner brick / icon.
Save.zip's contents go into the saves folder; Add-On.zip's contents go into the Add-Ons folder. You do need to have the add-ons both unzipped and enabled or the save will not load/show correctly.
A word to the wise (the dumb may skip): The print bricks are NOT complete, because you never see anything but the front in the Tutorial so I didn't bother banging my head figuring out how to get the textures to be correct. (I could barely get the prints the right way up, I didn't want to wade through more hassle.)
If anyone wants to finish the print bricks and send me the "proper" bricks' .bls, as it were, it would be greatly appreciated.
EDIT: That's not where that apostrophe goes...
EDIT: Changed the file - you'll need to redownload if you got the older one.
EDIT: Fixed the direction the Wrench was facing.
EDIT: Updated both the Add-Ons and save of the pack.
EDIT: I used the wrong colorset to save with. Not a major issue but it might cause some color problems.
