I wanted to make something really simple, yet useful. So, I came up with this. It's nothing special, just a bunch of primitives for building stuff, plus some chamfered(beveled) primitives and an archway.
If you want to give it some colours, use the colour tool. That's why I made it grey.
IF YOU THINK IT'S TOO STUPID/SIMPLE, GO AWAY. IT'S USEFUL FOR CONTRAPTIONISTS/BUILDERS!
