The design is quite impressive. While it does require a significant amount of filament, the end result is well worth the investment of both material and time. The build is very solid and functional. My only minor concern was some warping on the front left section, which led to slight alignment issues. I resolved this by extending the threaded section of the vent shutter screw by double its original length, which allowed the knob to clear a misaligned seam. It now functions perfectly. I am currently in the process of printing the double-space Raspberry Pi shelf.
