Summary The very first upload in our "Unlimited Adventures" line of accessories and playsets for 1/18 scale (3.75") action figures. Included are two versions of an oil drum, great for serving as a backdrop for industrial scenes or (in the case of the open version) being filled up with cargo or contraband. Enjoy! And be sure to keep an eye out for more 1/18-scale goodies. How I Designed This I created the base oil drum in FreeCAD, then used OpenSCAD to cut it apart into a body and the lid, as well as to boolean out the cavity for the open version.
