Description
This is an enclosure/case/box for the Pico/2 Computer published in Silicon Chip magazine April 2025 issue. The Pico/2 Computer is a complete computer based on a Raspberry Pi Pico 2 (RP2350A). It boots to a built in BASIC interpreter and editor, just like the early Personal/Home Computers of the 1980's.
After acquiring the mostly-assembled official kit and soldering the Pico 2 onto the main PCB, I looked at the recommended case (Multicomp MCRM2015S) from the recommended supplier. With freight they wanted over AU$40 ! Then you still have to cut out the connector openings.
That was enough of an excuse for me to spend a Saturday evening with my favourite 3D design tool and Bambu P1S printer.
This case is designed to house the official kit PCB. It includes PCB standoffs and a snap-on lid with custom inlaid text labels for the Pico/2. It of course has all the openings for the connectors. The PCB standoffs include holes to fit the screws provided with the kit (M3x6mm pan head machine screws).
I printed this without supports on a Bambu P1S, using PLA. I recommend using AMS for the multi-colour to get the inlaid text on the lid, but you could do without it.
Results may vary with different printers, filaments etc.
Insert the PCB down on an angle, HDMI-side first, into the connector openings, then lower the USB side in - perfecto!
The lid just push-clicks on. To remove the lid, tip the case upside down, a slight gap will appear under the lid, enough to get a pry tool/blade under one of the non-connector sides, then just lever it open. It pops off easily. To finish off, I stuck rubber feet on the bottom.
Enjoy!
