I've had this one planned for quite a while, just have been too busy to get to it until recently.
Outer dims 43 x 24 x 14 (62 gallons)
Material is all 3/8" with a black back and black bottom, internal overflow 1/4" black, external overflow 3/8" clear.
All parts cut on a CNC router
Here are a few renderings of the final product.
Rendering - Front
Rendering - Rear
There were a few changes, I shortened the length of the internal box, added a hole for a 1/2" return bulkhead, and reduced the external box to one drain instead of 2.
Here is the front/back/sides bonded together
It's sitting on the euro top and the bottom panel
Internal and external overflow boxes getting bonded
Will finish overflows today and bond the internal one, then it sits for a day to cure...
