Your project panel looks unfinished because that cheap plastic knob doesn't fit the vibe. This 16mm black anodised knob is solid aluminium with grub screws for a locked-in fit. Suits a 0.25-inch (6.35mm) shaft — the standard pot size on most boards. Drop it on, tighten the grub screw, and your build looks like it belongs in a proper rack unit
