Summary

Stand features rotatable legs for more compact storage. Rubber bands are used to retain the leg tabs in their slots. Stand angle is 35 degrees. The stand pieces fit together without hardware.

Print 2 sets of the stl file items. You might need to print the "key" part with a brim as it is quite small. And you will probably need to file or grind the edges and slots to ensure a good fit of the key into the support piece. Drill through the 4 bridged holes for the screen mount with a 3mm (1/8") bit to allow the screen mount bolts to pass through. The hole in the support piece should be reamed out with a 4.5 mm (3/16") drill bit to ensure the key can rotate easily. Use a #19 rubber band, double-looped to secure the key in the support as shown in the picture.

Make sure the leg is oriented in the correct direction before locking it into the key. The key is held in by hidden latches - it will be very difficult to separate once it's put into the leg. The supports are fastened to the display with four M2.5 x 8 bolts.

To fold the legs, just pull them slightly away from the supports (so the tabs clear the slots) and then rotate 90 degrees to the other slot positions. The rubber bands should hold the legs so they don't fall out of the slots.
