Raspberry Pi case
by HansH, published
The Raspberry Pi is a creditcard sized computer which you can buy for $25 or $35 (depending which version)
Never designed a case before, so perhaps things can be better...
v11 Different splitlevel (more simple) on backside keep a little margin on back split, so that top and bottom always fit added openlogo option added pcbholder option changed support studs a bit changed dimensions to 85.0 x 56.20
v12 Different component locations/sizes keep a little margin on component holes pcbsize to 57.0 x 86.0 (actual it is 56.17 x 85.0) made casestuds wider and added 2 minor holes for self tapping screws
v14 Got a RPI.. so production board measurements...
v15 moved the rca and snd a bit to get them more centered Thanks to lincomatic at Thingiverse Added option for GPIO side hole in bottom or top Added showing GPIO pins with component drawing
If it fits or doesn't, please let me know..
The bottomholder_frame.stl is a standlone minimal frame for a RPi. All the other bottom_xxx and top_xxx.stl files can be combined. If you want something specific just take the openscad file and alter it, or just ask...

// All parts are draw as default just disable the ones you don't want DRAWfull = 1; DRAWtop = 1; DRAWbottom = 1; DRAWtopinlet = 0; DRAWbottominlet = 0; DRAWpcb = 1;
GPIOHOLE = 2; // GPIO opening in : 1=bottom 2=top GPIOsize = 2; // define height of gpiohole
If you draw 1 part, it will center, otherwise multiple parts are showed.
You can control the case looks by changing : topframe = false; // if false, underneath values determines how topinlet = false; // false is outside, otherwise it is with an indent topholes = true; topmiddle = true; toplogo = false; toplogohole = true; // cut out logo, so you have a view on the pcb toplogosunken=false; // true or false, no idea if this works on a reprap bottomframe = false; // if false, underneath values determines how bottominlet = false; bottomholes = true; bottomscrew = false; bottomfeet = false; bottomsupport = true; // Added extra support locations for pcb bottomclick = true; bottompcb = false; // just a pcb holder without a top
Controlling the size of the case can be done by:
box_thickness = 2.0; // minimum = 2.0 for RepRap printing
Low box (red box in picture): inside_h = 12.1; // USB goes through deck, 16.5=full height pcb_h = 5.6; // room for SDslot and a deck
inside_h = 16.5;
pcb_h = box_thickness*2+3.5;
