Pivoting LCD frame for 20 mm extrusion

Works with Geetech LCD full graphic display. Mounts on 20mm V Slot extrusion with 2 M5 bolts. Requires M3 bolts, nuts, and washers to assemble. I am going to make or buy a M3 wing nut for the adjustment slide arm. Only has a normal nut in the picture.
Update: printed one of these off:

Works very nicely with a regular M3 nut.
If you need modifications let me know.
