pen jig 3d model

Design a precision, two-layer jig optimized for 3D printing on a Bambu Lab A1, intended for use inside an xTool F2 laser engraver. The jig must securely hold multiple pens or pencils in a flat, repeatable position for batch engraving, while fitting cleanly into the machine’s removable baseplate cavity. Overall dimensions and structure: The jig must be square with final outer dimensions of 107.7 mm × 107.7 mm to allow a snug but non-binding fit inside the xTool F2 cavity. Total height must be 14 mm. The model consists of two integrated layers forming a single printable part. The bottom base layer must be 5 mm thick and completely flat to ensure stability when placed inside the engraver. The top functional layer must be 9 mm thick and sit directly on top of the base, forming a combined solid structure. All geometry should be manifold and watertight, suitable for direct STL export and slicing. Pen slot configuration: The top surface must contain 10 parallel slots designed to hold pens
