The prompt
Design a 3D-printable reversible notecard holder for a Bambu Lab P1S used as a pen plotter. * Hold six standard 3 × 5 in (76.2 × 127 mm) notecards in a 2 × 3 grid. * Each card must be securely held **only along its bottom edge**, using a small lip/slot/clip. * Cards must be quick and easy to insert and remove without tools. * The retention mechanism must keep cards securely in place when the **entire holder is flipped 180°** to write on the opposite side. * Keep the entire writing surface of every card unobstructed so the pen can write close to all edges. * Include precise alignment features so the holder can be flipped and returned to exactly the same X/Y position. * Make it flat, lightweight, sturdy, and easy to FDM print with minimal supports. * Keep all features low enough to avoid interference with the P1S pen plotter. * Use millimeters and provide an STL, preferably with a parametric/STEP version.
