Hi, just a quick design, I made it for my pi 5 but should work with a pi 4b, i used 3mm wood dowel for the front grill and the rest pla and fuzzy skin to make the side and top panel look more like mesh, I also used magnets to hold the side panel on.
Sorry it is far from perfect and might need sanding.
