The Printrbot Simple Metal is a fantastic little printer, but I was surprised that it didn't come with a bottom. Even after securing the wires with zip ties, they tend to spill out. I decided to make a base that holds in the wires and absorbs vibration. I used Sugru for the feet, but I'm also providing a version with flat legs for those who want to use rubber feet, etc. . This design uses every bit of the Simple Metal's 150mm build volume. Print out two and then connect to form the base. See instructions for parts list and more info. .
