4-Bottle Rounded Organizer Base

Design a 3D-printable organizer base for 4 cylindrical skincare bottles arranged in a single straight row. All units in millimeters. Export as a single watertight (manifold) STL. STEP 1: ROUNDED RECTANGLE OUTLINE (MANDATORY, DO THIS FIRST) - Sketch a 2D rounded rectangle on the XY plane, centered on the origin: 182 mm long (X axis) x 50 mm wide (Y axis). - ALL FOUR CORNERS of this sketch must be rounded with a 12 mm radius. Do not leave any corner sharp or square. - The corner arcs must be tangent to the straight sides, with no kinks. - Extrude this rounded profile 25 mm upward (Z axis), bottom face at Z=0. - The block seen from above must look like a long pill-shaped rectangle with softly rounded corners, like a Mac mini. STEP 2: OUTER EDGE FILLETS - Apply a 2 mm fillet to the entire top outer edge and the entire bottom outer edge, following the rounded corners all the way around. - The 12 mm vertical corner rounding from Step 1 must remain intact. STEP 3: BOTTLE POCKETS - Cut 4 circular pockets, each 34 mm in diameter, in one straight line along the X axis. - Pocket centers are at Y = 0 and X = -66, -22, +22, +66 mm. - Center-to-center spacing is exactly 44 mm, leaving a 10 mm solid wall between neighboring pockets. - Each pocket is 22 mm deep, measured from the flat top face, with a flat bottom. This leaves a solid 3 mm base under every pocket. Pockets are blind holes, not through-holes. - Pocket walls are perfectly vertical with no taper. - Leave an 8 mm solid wall between each pocket and the outer edge on every side (ends and long sides). STEP 4: POCKET RIM FILLETS - After cutting the pockets, apply a 2 mm fillet to the top rim of each pocket (smooth rounded lead-in). The 34 mm diameter and 22 mm depth stay unchanged. The fillet only widens the opening at the top. FINAL CHECKLIST (verify before exporting) - All 4 vertical corners are visibly rounded with a 12 mm radius. - Top and bottom outer edges are filleted at 2 mm. - 4 pockets, 34 mm diameter, 22 mm deep, 44 mm center-to-center, with 2 mm rim fillets. - Overall size is 182 x 50 x 25 mm. CONSTRAINTS - One single solid body, no separate parts. - Flat bottom, no overhangs or supports needed. - No text, logos, or decorative features. - Do not change the stated dimensions. If any value conflicts, prioritize: pocket diameter (34 mm), pocket spacing (44 mm center-to-center), overall height (25 mm), 12 mm corner radius.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
