My Son purchased a cloth green screen for his computer gaming multiple monitor monstrosity.  I searched multiple model sites for a “T” rail drop ceiling mount that would hold the cloth screen and only could find hook or . I found a small drop ceiling clip by solarbotic on thingiverse and an openscad tarp clip2_scad file and developed the clip. I cut and modified solarbotic’s mount to the tarp clip scad to create this final version.  It grips the cloth material well and can be easily taken down when not in use. 

*Each clip uses one M4 x 16mm hex head screw and nut
