When a broken hinge, missing knob, or cracked piece puts a favorite tool or everyday object out of commission, replacing it isn't always an option — but printing it yourself is. 3D Printing Spare Parts teaches you the principles of design while solving real problems — repairing broken items, replacing discontinued parts, and producing useful objects that would otherwise require costly orders or full replacements. Through hands-on projects that build skill from simple fixes to complex creations, you'll learn to design custom, precision pieces tailored to your exact needs, on your own schedule.
