This is a sun-shade made for 9 inch LCD monitors when used outdoors (for things like FPV and what not). The shield is split into left and right so they can be printed separately. Both parts have 1/8 inch holes that are 3 inches deep per side (so you'll need 1/8 inch rods that are 6 inches long). This helps with assembly and alignment. How it is attached to the monitor is up to the user. Slight scale adjustments may be necessary for a correct fit.Six 1/8" x 6.00 rods are required for assembly/alignment. Velcro or other material is needed for mounting to a monitor.
