The prompt
Design ONE slider holder for a 0.5 cm dia LED (body length 0.9 cm), 3D-printable. Units cm, FDM. Axes: X = slide direction (the FRONT face touches the test tube), Y = width, Z = up. Main plate: Y width 3.0, X thickness 0.5, Z height 4.5 (Z from 0.05 to 4.55 above the box floor, slides directly on the floor with 0.05 gap). LED hole: dia 0.52, through the plate at Y centre, Z=3.0. The LED is pushed in from the back so its tip is flush with the front face and 0.4 of the body sticks out behind the plate. Front bottom: arch cut-out 1.4 wide x 1.1 high, centred, so the holder clears the test tube seat when touching the tube. Side face towards the front wall (Y=0 side): round boss dia 0.5 flush with the plate side, at Z=3.0 and mid-thickness, with M3 screw pilot hole dia 0.25, 0.8 deep. Must slide 0 to 3 cm (moves away from the tube towards the end wall). Export STEP + STL.
