Summary

This will fit a standard Nokia 5110 display based module like a glove. The inner room should come out at around 44x44mm. The bezel blocks the light emitting from the side, and hides the non-drawing area.

Made in Sketch-Up. Extrude the outer border to create a casing for the display. The Studs can be used to mount the display with screws, but that isn't always needed.
