The prompt
Design ONE 3D-printable part: a flat lid. Units mm. Single solid. Print orientation: flat, top face up, no supports. Must fit on a 220x220 mm plate. - Plate 100 (X) x 35 (Y) x 3 (Z). - Test tube hole: 23.6 mm diameter at X=50, Y=17.5. - Two slots along X at Y=17.5, each 4.2 mm wide: left slot X=1.9..36.1 and right slot X=62.9..97.1. Rounded ends. At least 1 mm of material between each slot and the tube hole. - Engraved scale (0.4 mm deep) on the top face, 6 mm to the +Y side of each slot: - Left scale: tick every 5 mm, long ticks with numbers 0, 1, 2, 3 (cm) at X=34, 24, 14, 4. "0" is the end nearest the tube. - Right scale: same, at X=65, 75, 85, 95. - Text height 4 mm. Add the small label "LED" near the left scale and "TCS" near the right scale. - Clip notches: 4 notches on the top face at the long edges (Y=0 and Y=35) at X=20 and X=80. Each notch is 9 mm (X) x 3.5 mm (Y, from the edge inward) x 1.2 mm deep.
