This is a simple flange for a cosmetic application. The glass cosmetic cover for an Amana oven shattered when the oven was being moved. An aluminum sheet was chosen as a replacement, and two port holes were drilled into the plate to allow viewing of the interior of the oven. The actual door of the oven contains a tempered glass window. The size of the rim is 94 mm. I'll set the feature to allow you to download the stl if you would like to make one of these for yourself. If you would like to order one from Shapeways, and you would like a color other than white, please let me know. If you would like to order one from Shapeways in a size other than 94 mm, I'd be happy to make the adjustment and offer the new size.
