Sally Hansen Insta-Dri Nail Polish Holder

Summary

This is a custom-designed holder for Sally Hansen Insta-Dri nail polish bottles. It features nested wells for efficient storage, rounded corners for aesthetics, and a slightly domed top for a polished look. The layout alternates 3-bottle and 2-bottle rows, maximizing space while maintaining accessibility.

This design is fully parametric, meaning you can easily modify the number of rows, spacing, and other dimensions to suit your needs.

✔ Optimized Nesting – Alternating rows of 3 and 2 wells save space.
✔ Parametric Design – Easily adjust dimensions and layout in OpenSCAD.
✔ Rounded Corners & Domed Top – Gives a smooth, polished appearance.
✔ Consistent Spacing – Ensures easy bottle placement and removal.
✔ Secure Fit – Designed to match the bottle footprint while allowing easy access.

•   Bottle Footprint: 36mm x 12mm (tapered trapezoid shape)•   Bottle Well Depth: 18mm•   Bottle Height Allowance: 60mm•   Spacing Between Wells: 8mm•   Row Spacing: 4mm•   Pair Spacing (3-to-2 Transition): -6mm (slightly offset for a snug fit)•   Base Height: 30mm (including 8mm solid bottom for stability)•   Rounded Corners: 5mm•   Dome Height: 3mm

This holder is parametric, meaning you can adjust:
• Number of rows (layout array in OpenSCAD)
• Spacing between rows (row_spacing and pair_spacing)
• Bottle well dimensions (adjust footprint, depth, and height)
• Base size & thickness
• Dome scaling

Simply edit the OpenSCAD file to adjust these parameters and generate a new STL for printing.

•   Material: PLA / PETG / ABS•   Layer Height: 0.2mm (or finer for smooth walls)•   Infill: 15-20% (for balance between strength and speed)•   Supports: Not required•   Brim/Raft: Not necessary unless bed adhesion is an issue
