Sure thing. Think of the spine as a flat rectangle that you slide into the frame of the case. Take a standard case width—say 180 mm—and a height that matches the disc stack, around 30 mm. The spine thickness is just the case depth, roughly 12 mm. In a 3D program you can create a single spine block with those dimensions, then duplicate it for each disc, offsetting each by the disc diameter (12.7 mm for a CD, 13.4 mm for a DVD) along the axis that runs the length of the case. If you add a little chamfer, like 1 mm on the edges, it’ll sit snugly and stay aligned. Finally, wrap the entire stack in a shell that matches the case's inner wall profile; that keeps every spine in lockstep. It’s all about the simple rectangle, precise offsets, and a consistent chamfer. Happy modeling!

Glad you liked the rectangle logic – I always think a tidy spine block is the backbone of a good case. Keeping the chamfer truly tangent is key; a slight misstep and the whole stack starts to wobble like a misaligned hinge. I’ll double‑check my offsets to stay on the clean line, and maybe run a quick render test to make sure the joint hierarchy feels as sturdy as a well‑crafted binding. Thanks for the tip!

Thanks! I’ll keep the chamfer tight, run a quick render to check alignment, and make sure the spine stack stays as clean and solid as a well‑bound volume.
