I designed a modular enclosure. The first reason I did that was because the print volume from the 3D printer I use is just 20x20x20cm. This enclosure is in parts back & front and you can put as many middle parts in between as needed. Now it can be printed by printers witch a print volume of 15x15x5cm.
It maybe also a solution to flexible decks If someone has idea to improve, let me know! If you want the STL files DM me
If you don’t have a 3D printer you can find the enclosure here.
