The Virtual Boy stand is a fragile thing. The clip on mine had long ago snapped, rendering the device useless. I made up this replacement for it in Fusion 360.

The version in the photos was made from PLA and printed out almost perfectly. Almost no cleanup needed, aside from removing the supports.

CAUTION: Be careful how you orient your print, as the layers are weaker along different axis, which could lead to the clip breaking and the Virtual Boy falling off the stand. I recommend printing on the bed in the orientation the included picture shows.
