fidget keyboard base 3d model

Use the uploaded photo as the exact reference. Recreate the SAME physical fidget keyboard base underneath the keycaps. Remove ALL keycaps and decorations. Keep the exact original key positions, spacing, proportions, row arrangement, long keys, vertical key, and outer case shape from the reference photo. Do NOT redesign or regularize the layout. Create ONLY the empty 3D base/case with recessed key wells and the mechanical retaining/guide structures underneath each key. Rounded brown plastic case, realistic thickness, solid 3D geometry, clean manufacturable surfaces. No electronics, no switches, no wires, no keycaps, no cat-shaped parts.
