This bracket will allow you to mount a GeekPi case onto a UGREEN external drive enclosure.  There is an air gap between the case and enclosure to allow air to circulate around the GeekPi case.  I use this for my Home Assistant build.

Requires 4 M2.5x16mm SHCS to attach it through the GeekPi case, then slips over the UGREEN enclosure.
