29. Make A Mechanic's Workbench
You will want to create a foldable workbench conveniently set up in seconds for others who spend more time under the hood. Two or four, a pair of solid hinges, threaded pipes and flanges, and several screws are all you need for this build.
The workspace can include a surface made of a 30-inch solid core door, or you can use other materials when considering your supply. The mechanic's workbench can be set up by screwing the pipes into the flange.
