The first group buy for MFR cases ran for 2 days on September 13+14th, 2021. Cases were available for $95 and came with seven M4x2mm screws for tray-mounting the PCB and a 2mm laser-cut case foam. Addon carbon fiber switch plates were available for $20.
MFR is a high-profile, single-piece tray mount case with large chamfered bezels. The case uses the same seven tray-mount holes and M2x4mm screws as the MiniVan aluminum case and other tray-mount MiniVan cases. The bottom of the case is completely flat with no recesses for bumpons or holes for screw-in feet. There is no hole for accessing the reset button commonly found on the underside of many PCBs.
There has been great interest as to the meaning of "MFR" with many people assuming it is an acronym, possibly including the words "MiniVan" or "Rain". Rain won't say so we will continue to speculate.
The case is compatible with standard MiniVan tray-mount plates. Plate files can be found on the Files page.
Several prototype units were created from aluminum and milled acrylic to evaluate the design.
Clear acrylic and raw aluminum units were created to test the milling process for the first round of prototypes. Milling results were fantastic but it was discovered that the thin section of material below the USB port cutout was prone to breakig. The design was altered and a second round of prototypes were ordered.
Following a minor redesign, multiple materials and colors were tested, including frosted acrylic, sandblasted + anodized aluminum, and powder coated aluminum. The second round of prototypes have a notch below the USB port to alleviate the issue with damaged cases from the first batch of prototypes.
The first round of metal cases were available during a group buy in September 2021. 50 total cases were produced - 20 silver and 10 each of gold, blue, and purple.
