Regarding white, black, and red, I can accommodate changes even after purchase if you leave a comment. This is a custom 3D-printed cover for a Wonderswan Color and Crystal USB power supply unit. (This is a set of the power board and cover) Conventional Chinese power boards had tall components, resulting in a bulge similar to a regular battery case. However, around the end of 2024, a new power board appeared with lower component heights, allowing for a flat cover to be attached. I tried to print it as cleanly as possible, but it's a layered print, so it has a slightly jagged feel, but please understand that this is typical. With translucent colors, the LED is visible, and the print seams are slightly visible, which is the current product specification. (See photos) Opaque colors like white, black, and red make the LED almost invisible. (Black is practically invisible) Power is supplied via a USB-C connector, and any standard 5V output is acceptable. (USB-PD is not supported) No other items are included besides the power unit and board cover. The board cover is made of PLA resin and is sensitive to high temperatures. Do not leave it in a place exceeding 40 degrees Celsius, as it may deform. Other colors will depend on the availability of affordable filament, so please leave a comment with your request, and I will check if it's possible. For those who already have a power board: If you only want the cover, please ask in the comments. However, due to individual differences in the soldering of the board, the metal fittings may be raised, and it may not fit as is. This is intended for those who can modify it by trimming, etc. Currently, it's Ver.0.47, and I'm periodically reviewing the shape.
