Raspberry Pi 4 Project Enclosure

I've designed this for a 3D Printing enclosure controller I'm building using a Raspberry Pi 4.

Design Features

• 1.6mm thick walls for sturdy construction
• 4 x 11mm knockouts for panel mount DC barrel jacks
• 4 x 6mm knockouts for panel mount 3.5mm jacks
• 3 x 20mm x 3mm slots for ribbon cables or other wires.
• Mounting posts for M2.5 brass inserts for Raspberry Pi 4
• Mounting post for DC-DC converter if you wish to power the Pi via GPIO (best to add protection circuitry if you do)
• Mounting posts for M2.5/M3 bass inserts to support other components
• Lid secured via M3 bolt into M3 brass insert on base.

Printing

Suggest using PETG, not sure how well PLA would hold up over time.

• Main Body:
  • Material: PETG Prusament Anthracite Grey
  • Print Settings (PrusaSlicer): 0.20mm Quality, 15% infill
  • Supports: None
• Lid:
  • Material: PETG Prusament Anthracite Grey
  • Print Settings (PrusaSlicer): 0.20mm Quality, 15% infill
  • Positioning: Print the lid top side down.
  • Supports: Ideally paint on some supports for the small lips that lock into the base. Or select support on build plate only.

Hardware

• Raspberry Pi 4
• 12/24V to 5V DC-DC Converter:
  • 10A (50W) version
  • 3A (15W) version
• 2.5mm DC Barrel sockets and jack plugs
• 3.5mm 3 pole chassis socket and 3.5mm 3 pole plugs
• 3.5mm 4 pole chassis socket and 3.5mm 4 pole plugs (these connectors may require the holes to be enlarged slightly).
• M2.5 Brass inserts
• M2.5 x 5mm bolts (for Pi)
• M3 Brass inserts
• M3 x 8mm bolt (for lid)
• M3 x 4mm for DC-DC Converter and other mounting points

Additional Notes

This is my original design taking some inspiration from Dan Andersen's Compact Fysetc Spider and RPI 4 Case and 120mm Fan 
 

Version History

• V11 - Initial Release
• V13 - Fixed gap between case wall and mounting bolt area. Smaller knockouts now 6mm, increased spacing between smaller and larger knockouts.
