As-thin-as-it-gets hard case for the Anbernic RG406V (and probably the RG405V).
Print the three parts separately, only the joystick cutout should require supports. Use 1.2mm x 31.8mm wire brads for the hinges like in the original. Glue the joystick cutouts into the lid from the back with superglue. As recommended by the original designer I lined the bottom and screen area with felt for protection and a snug fit.
This redesign should still fit the RG405V although I haven't tested it - please let me know if you have!
The author remixed this model.
I redesigned the top of the case to fit the (taller) RG406V while also making it thinner, with cutouts for the joysticks. This makes it much more portable, with the downside of the lid having to be printed in two parts and glued together. The bottom part is identical to the original.
