Summary

Building on top of HansH's original Raspberry Pi case, and several derivatives, here is another version with a GPIO access window on top (ideal for attaching jumper wires), a tray to guard the SD card and a small window to see the LEDs.

Instructions

I printed this on a Makerbot Replicator 2 with 1.75mm PLA filament and the build turned out to be fine (but see notes below).

ReplicatorG GCode settings used

  • Slicing Profile: Replicator 2 slicing defaults
  • Use Raft/Support: No
  • Use support material: None
  • Use default start/end gcode: Yes
  • Use Print-O-Matic: Yes
    • Settings
    • Object infill (%): 25
    • Layer Height (mm): 0.27
    • Number of shells: 2
    • Feedrate (mm/s): 80
    • Travel Feedrate: 150
    • Print temperature: 240
  • Plastic
    • Filament Diameter (mm): 1.75
  • Extruder
    • Nozzle Diameter (mm): 0.4
    Estimated build time: 41 min Notes With 25% infill, 2 shells and the default medium resolution (.27mm) of Replicator 2, some very small regions in the R-Pi logo on top did not get filled. There might be scope for improvement in slicing algorithms here, but greater infill, a single shell or finer resolution may solve the issue (note that 2 shells actually means 3 because one perimeter is generated regardless). Some filing may be necessary to get a good fit.

Did something similar myself. Discovered the GPIO access wasn't deep enough. It needs to wrap around the side a little bit to give better access.

Top STL seems invalid.

Yup, my bad. I've uploaded the correct file. Let me know if you still have trouble - thingiverse is taking ages to update the preview (does anyone else have that problem?).
