Electronics Mounting Plate

Create a separate electronics mounting plate for my Robofest robot with the following exact specifications: overall size 140 mm × 100 mm, thickness 3 mm, and corner radius R8 mm. Keep it smaller and centered relative to the existing 170 × 120 × 3 mm battery plate. The plate should be a clean, simple, professional design intended for mounting the controller, motor driver, wiring, and other electronics. Do NOT copy the bottom chassis hole pattern. Do NOT add motor holes, axle holes, wheel cutouts, sensor holes, cable holes, or unnecessary decorative holes. Provide only the necessary 4 structural mounting holes for attaching the electronics plate to its standoffs, using Ø3–4 mm clearance holes, arranged symmetrically and kept fully parametric. Leave a large unobstructed central area for electronics and wiring. Fully constrain the sketch, keep all dimensions editable, maintain symmetry, and ensure the plate is manufacturable and free from rebuild errors. Do not modify the existing bottom chassis or battery plate. Create it as a separate SolidWorks part and make it compatible with SLDPRT and STEP/STP formats. Final geometry: a clean 140 × 100 × 3 mm electronics plate with R8 mm corners and only the four necessary structural mounting holes.
