Mini Rack for Single Board Computers

thingiverse

I figured if your going to build a raspberry pi supper computer, why not build it in style.... This is very much a work in progress. Right now. The basic rails, couplers, and side panels are complete and working well. All holes are threaded for standard #6-32 computer screws. But may practical parts are still missing. (IE the actual board cases). This project was intended as a Raspberry Pi cluster case, but when defining the Mini Rack Unit specification allowances were made for most single board computer and micro controller boards currently available. There were a few single board computers that are just too big to be practical. Each rack is 7MU (minirack Units) tall. You can make larger racks using the included coupler to vertically connect two racks. You will need at least a 180mm bead for the basic rack (side rails can be printed diagonally). Some parts (like the side panel) will require a larger build platform. 1MU is defined as 99mm Wide 24mm Tall and no more than 150 mm Deep. There are three mounting Holes on each side of the rack. The Mounting holes are 105mm apart horizontally, and placed vertically at 4mm 12mm, and 20mm. The rails themselves are designed to allow .5mm above, bellow, and on ether side of the case (actual clearance is 100mm x 25mm). To do: Design single board computer cases to populate the rack Design horizontal coupler to connect racks side by side Build plates for interconnect (keystone for Ethernet, or power barrel connectors for example).
