We'd love to hear from you if the print was successful.

When I upgraded my PrintrBot Simple Metal Silver with a hotbed it caught on fire! YIKES! So I moved my PrintrBoard out from under the hotbed to reduce the resistance in the power cable caused by increased heat which caused the fire by creating an increasing cycle of heat and resistance. Well having a PrintrBoard just sitting on my desk was not safe either, plus it presented a couple of opportunities to make an enclosure for my Printrboard, include a cooling fan and also cool and enclose my Raspberry Pi that I use as a slave for my PrintrBot using AstroPi (AstroBox) from AstroPrint.
I have a Rev.D Printrboard and a Raspberry Pi 2, so the files are specific to these hardware, but I have included SolidEdge part files for those with either SolidEdge or SolidWorks to modify for their specific hardware or just their own style. I also Included versions without logos, as well as the logo files in AutoCad and SolidEdge format. I have since upgraded to a Printrboard Rev. F, and the enclosure still fits fine.
Some files include insets for nuts. I based all of the hardware on 3mm bolts and nuts except for the Raspberry Pi 2 mounts which are 2.5mm. If a nut inset is not present it is because I usually use a tap for those holes as ABS and PLA both tap very well.
It is worth noting that to use this enclosure as I have designed it I am drilling a 19mm (~3/4 inch) hole in the side of my PrintrBot Simple Metal Silver for access to the cables. After you print your parts they can be used to mark the hole placement right where you would like it to be mounted.
Materials and methods
Printing the enclosure will require printing support material. In my experience I have liked the freeware MatterControl for their support material feature Support Everywhere which allows support material to be started within the part and not originate from the print bed. For those of you lucky enough to have the paid for software Simplify3D, this feature is also available.
You don't have to print all the parts! Just use the ones you want, some are variations of the same part. Some are just logos for fun.
I kinda like anything Fallout !!!!
