LisaFPGA Case — a 3D-printable "pizza box" for your LisaFPGA (Rev 3)

Hey everyone,

Some of you have followed my case progress over in the main LisaFPGA thread — thanks for the interest! I'm giving it its own thread here so the case chatter doesn't crowd out the board discussion.

Quick recap if you're just seeing this: my LisaFPGA had been sitting on the bench without a case since there wasn't one at launch, so I fired up Fusion and made a simple one. It's finished now, and the files are up for anyone who wants to print one.

It's a basic slab / "pizza box" style enclosure:

• Cutouts for all the ports, except the 4-pin twiggy header. **
• Lift-off lid for quick access to the switches, jumpers, and LEDs
• Vents over the FPGA for cooling, plus a grille over the speaker
• Four M3 bosses that line up with the board's mounting holes
• A black & white "LisaFPGA" badge for the lid

** I have no Twiggy drives and I needed the extra plastic for strength of the case on right side, so I decided to omit the opening for header.

I printed and verified mine on a Bambu Lab X1 Carbon in PETG HF (Beige) on a smooth PEI plate. The repo has a ready-to-slice .3mf laid out for the X1C, plus separate tray and lid STLs if you're on another printer. Supports are required (already enabled in the .3mf).

And a big thanks to Alex (alexthecat123) for the LisaFPGA itself.

Below are photos of the case in use. The lid appears slightly unusual in the photo. I ran out of the beige filament halfway through printing the current design, which is why half of the lid is white. I had already used two other rolls of beige filament in an attempt to achieve the correct fit for the PCB. I plan to print another case in a solid color once I order more filament.

Nice work!
