Arduino Leonardo with USB Host Shield case

prusaprinters

Basic case for Arduino Leonardo with USB Host Shield built using YAPP-Box in OpenSCAD. Only the USB ports are exposed, but headers could be easily exposed with an additional opening in the .scad config. External push point for the reset button.Printed on draft with paint on supports under the big square opening and everything brimmed. Push button hole was a little dirty without supports, but some quick knife work and pushing the button a few times smoothed everything out.Use M3x8mm screws to attach the Leonardo to the bottom of the case, insert the shield, and then snap on the lid. I think you're supposed to glue together the two small pieces to make the reset button extension, but I just stacked it upside down, put it together, and moved on. USB Host connector (the USB-A socket) is fairly recessed, but I didn't have any issues plugging my keyboard in.I use this as a usb_usb converter running QMK for remapping my keyboard without requiring hardware mods to the keyboard itself. GitHub: https://github.com/michaelansel/3D-Models/tree/main/LeonardoUsbShieldCase
