Last year I bought a Printrbot LC on behalve of the school where I teach. After building the kit and a summer-vacation for figuring out, and getting used to, the machine it was time to let the beast out in to the wild. Because it can be quite risky to let my middle school students around something rather fragile en expensive I decided it needed some sort of protection. Besides it had to be portable so my colleagues and me could use it in different classrooms around the school and bring it back to the storeroom after use.
I first made a kind of "Microwave" box around it but, however it was good for transporting the printer to the school, I realized this wouldn't work with storing the rolls of filament and the PC connected to printer.
If you are familiar with education you will know that (no) low costs and quick solutions are primal. So when the people from the school cleaning company disposed an old cleaning trolley I took it and used it as a start to build this car. Some plywood, tie-rips and phillips screws completed the thing in two or three free hours in my teaching schedule.
It is far from perfect, let alone complete but I made it sketchy on purpose (yeah right...) so it can be adapted when needed and it isn't a catastrophe when it is abused.
This Instructable isn't really a step by step because I didn't documented the steps and only took pictures afterwards. It is merely a collection of construction idea's which you might find useful as an inspiration for your own projects.
