Raspberry Pi Enclosure
A materials list and STL files are provided here for 3D printing and assembling an enclosure for ShootPoints-Web running on a Raspberry Pi 3 Model A+.
- Raspberry Pi 3 Model A+
- 14 × 14 × 8mm heatsink
- Panel-mount USB type A extension cable
- Panel-mount micro-USB extension cable
- Threaded inserts, Brass, M3 × 0.5mm
- Screws, M3 × 0.5mm Thread, 10mm Long
- 5mm magnets
- (optional) White LED
- (optional) 100Ω resistor

Recommended print settings are 3 layer thick walls and 15% honeycomb infill, with either PLA or PETG. PLA tends to warp in the hot sun, so you may need to tape the two halves together, so for that reason PETG is recommended. Supports are recommended around the power and data ports of the enclosure base, as well as under the hook if it’s printed flat.
- Attach the USB cables to the enclosure bottom with the screws provided.
- Press the magnets into their pockets on the corners of the case bottom and top, making sure that the polarity is correct to hold the pieces together. If necessary, secure the magnets with a drop of super glue.
- With a hot soldering iron, press the brass inserts into the holes on the underside of the enclosure bottom.
- Attach the hook to the case bottom with the 10mm long M3 screws.
- Stick a heatsink onto the Raspberry Pi’s CPU chip.
- Set the Raspberry Pi into the case bottom with the MicroSD card to the left and the heatsink up.
- Plug the USB cables into Raspberry Pi and route them so that it all lies flat.

Instead of simply trusting that the Raspberry Pi is powered on, you can install an LED through the enclosure top to show its status.
- Solder one of the legs of the LED to the 100Ω resistor (it doesn’t matter which leg).
- Solder the other leg of the LED and the free end of the resistor to 10cm wires.
- Insulate the LED legs with heatshrink tubing so that they don’t short circuit.
- Attach female GPIO connectors to the free ends of the wires.
- Connect the LED’s anode to GPIO pin 26, and its cathode to an open ground pin.
- Drill a small hole through the enclosure top in the middle of the short empty tube on its inside face.
- Press the LED into the tube and glue to keep it in place and seal the hole.
