Pi PICO-W Slim Case [SNAPS TOGETHER - no glue] (with and without headers)

What is it:

It is a super slim case for the Raspberry Pi Pico W microcontroller.

The case snaps together.

No glue, no fasteners.  The no glue part was important because at any point you may want to pop it loose of the case and put it on a breadboard or wire it into a project.  Adding fasteners would make it harder for someone to replicate.

There are currently [ 3 ] versions.

•  A fully enclosed case, with no access to pin headers.
•  The same design, but with cutouts for pin headers.  Breadboard Compatible!
•  Key-chain Variant (fully enclosed).

The cutouts for the pin headers remove a lot of structure, so please use care when removing it from your build surface.

Standard:

With Header Cutouts:

Why:

I like being able to experiment with micros outside of a breadboard environment, and I find having them just hanging around without a case to put the fragile reset button at risk.  So, I designed a slim case that snaps together.  Glue would be easier, until you wanted to take it out of the case.

In the past I've used an 8266 or ESP32 as a sort of wireless adapter with my phone when diagnosing certain pieces of equipment that use custom 2.4ghz wireless protocols, so access to the USB port is all that was needed.  Having a slim case on it lets me toss it in my bag or pocket without as much concern of damaging it.

How:

This is a tight fitting case.  I did not design in big tolerances to accommodate printers that are out of tune, because I cannot possibly compensate for every variation of over or under-extruding printer.  The reason is simple: to make it snap together without glue, and stay slim, it needs those tighter tolerances.

If you have trouble printing this, I have a guide that should help you ensure you get true to dimension prints.

The top half of the case needs to be flipped over in your slicer so it lays flat side down. I had limited time to set everything up - I may correct its orientation later.

PRINT SETTINGS:
PLA recommended (works better in a rigid PLA than it does in a more flexible PLA+)
0.40 Nozzle
0.40 line width
0.20 line height
Outside Perimeters first
no raft
no supports

I recommend against using my gcode file.  It is tuned for my modified printer.  Its purpose here is to give information about estimated filament usage and print time.
