Snap-fit caddy/cassette/cage for the Pi Pico, intended to secure the board to a 3D printer that has 2020 extrusions as part of its assembly (such as Ender 3 models). Alternatively useful as a fashionable outfit for the Pico.

Optional deeper version encompasses the headers fully, and either version can be printed without the 2020 arms.

Warning! Snug fit. If your board has headers/pins, you need to be very delicate. Carefully separate the arms while holding the caddy, without snapping them off, and help the board gradually climb along the length thereof.

It goes without saying that you shouldn't attach it in the way of gantry movement, like I have in some of my demonstration images.
