I have very little pre-made stock. Mostly what is on hand is raw materials to make the cases with, so your case will be made in the order it was received in.

Because the cases are made on demand, there's no reason for me to sunset a design. If you purchase a set on the seconadary market years after it was discontinued by Lego, I should still have the design to craft a case for it. Limited releases are just a marketing gimmick to encourage you to buy now.

All of my cases are cast acrylic; 3mm and 6mm. All of it is designed, laser cut, prototyped, and made in my workshop. Optional case backgrounds are designed and UV printed in my workshop.
The panel connectors are anodized aluminum with m3 screws.
