This rear panel is a custom piece that only fits the Boxy Pixel Free Play Raspberry Pi aluminum shells. This fits the previous "slim" version only (prior to May 2020). Choose from black smoke color or a optically clear in acrylic, or black, blue or red aluminum. The Boxy Pixel logo is comprised of thru holes for venting.
The colored anodized parts have been anodized at a different time than the machined fronts. There may be some slight shade and surface texture differences between the machined front and these rears.
