This is a steel door on a small base, designed for use in a tabletop dungeon.
It measures about 1.5"/38mm high, 1"/26mm wide, and .5"/12mm deep. It prints without support on my Printrbot Simple 2014.
It is completely compatible with OpenForge and Dwarven Forge, and designed to fit within a one-inch-square doorway.
Thanks to my Patreon supporters for their contributions, which made this piece possible.
Printed with 30% infill at 0.1mm layer height.
