sorry felas i don't have the pics anymore,(exwife) i used to be an auto glass/ glazier man, i would cut mirror at size 12x 6 or in my case 18 by 32, but cut ur base, measure back,sides and top to fit leaving an angled front, if u can picture it, after u have the glass, it does need edge sanding(depending on how big its not expensive, use 1/4"mirror as base, 1/16 or 1/8 clear for sides, top and front) mate ur edges, to ensure fit, mask edges fine, clear silicone bead along mated parts( dont rush) and tape together for drying. as for ut u will love the reason 4 angled front parts ie 6" bottom and 5"top(sides need to match) after the whole case hase cured, mask only the bottom mirror to bottom of front, silicone it and tape it up, after drying u have a great cae with an opening front hinge, yes the silicone works and lasts, i use the same for fish tanks. i wish i had pics to show, just look at a fish tank, use mirro base and backs. i had 2 32x16x12 any 1 here should have no problem desiging this, go to ur local glass shop with ur specs. give a small one a try. u will love it.
