Enclosures are great to use in projects because they can protect your electronics.

This is a simple two part case let's you securely mount the Rasbperry Pi A+ to the enclosure using machine screws. It features openings and cut outs for each of the ports, so it’s easily to pass cables through.

The enclosure features cutouts for USB, HDMI, A/V, MicroUSB, GPIO, MicroSD and Camera/Display cables. Use #4-40 Phillips machine screws to secure the Pi to the enclosure. Cover easily snaps on and off. Case is 1.5mm thick. 

Tools, Parts, Supplies

PLA Material

PLA is recommened to minimize warping. Both 1.75mm and 3mm filament types will work.

Enclosure Dimensions

The total size of the enclosure is just a few millimeters bigger than the Raspberry Pi A+ PCB. It's only 1.5mm thick. 

Outside: 71mm(x) 63mm (y) 20mm (z)

Slicing Parts

Slice parts using your preferred slicer. Parts are oriented to be centered on your printers build plate. They require no raft or support material to print.

Parts tested were printed on Makerbot Replicator 2 using MakerWare and Lulzbot TAZ4 using Cura.

3D Printing Services

Check out 3D Hubs for a local directory listing of makers who own and operate desktop 3D printers that will print your parts for reasonabile prices.

123D Design

The parts were modeled in Autodesk 123D Design. The original solids are availbe to reuse, modify and customize the design. 

Installing Raspiberry Pi A+

  1. Insert Pi at an angle, with the corner going in first. 
  2. Press down and align up ports with the cutouts.
  3. Fasten four #4-40 Phillips machine screws into the mounting hoels.
  4. Place the cover over the top with the cutouts aligned up with the GPIO headers and camera/display ports. Press down to snap it into place.


You can stick this on to any surface using adhesives, double stick tape, zip ties or mounting tack.  Add little rubber bumper feet to keep it gripped onto your work surface.
