[DIY] Clip-In Holder for WIO Terminal - 3D Print

The WIO Terminal from Seeed Studio is my goto initial Arduino dev platform since it has most of the HIDs and features needed to get many projects started fast (buttons, joystick, screen, SD card, wifi, etc), before downsizing to a smaller or cheaper controller.

But seeing the price, which recently went from $20 to $30(!), I only use it as a plug-it-in-where-needed controller.

Hence this holder the WIO just clips into. It can now quickly be moved between projects. Simply connect the expansion port(s), done.

Fusion360 CAD, STEP, and 3MF slicer files are on Github

Happy Arduino projects and printing to all !

3D printing: tree support was enabled as the front catches are horizontal. The number of walls is critical (4 here @ 0.45 line width) as it needs to be high enough that the clip arms are fully solid and won't break in use:

For that same reason, printing 'by Object' was used when printing multiple parts at once, to ensure that layer adhesion remains high thanks to less cooling of the deposited filament between consecutive passes of the nozzle.

The backplate offers a number of holes for various mounting scenarios: holding screws in the front, back, or using the WIO's M3 inserts.

To install holding screws from the back, 4mm long M3 inserts must first be inserted:
