Modular 6-Bottle 3D-Printed Paint Organizer Uses Dovetail Snapping Racks

A compact, modular paint rack designed for miniature-painting bottles landed on Thingiverse, giving painters a simple, snap-together option for bench organization. Each module holds six bottles and connects to others via dovetail joins that snap together to form longer, customizable racks. The files include STL models plus a short build and print note to help makers get started.

The design matters because it trades bulky store-bought cases for a scalable solution that fits the ebb and flow of a painting session. Print a single 6-bottle module for a quick tabletop setup, or link several for a larger staging rack for a commission batch. The dovetail snap system keeps pieces aligned without permanent glue, so modules can be rearranged, transported, or stored flat between uses.

The model was posted January 25, 2026, and the Thingiverse entry supplies the raw print files needed to reproduce the parts at home or at a local makerspace. Designers and clubs can remix the STLs, scale modules, or add custom end caps and labels, making this a useful starting point for anyone looking to standardize paint runs or to share consistent racks at a club night or event.

Practical value is immediate. A six-bottle module cuts down on clutter around a wet palette and keeps frequently used colors within thumb reach. Expandability means you avoid buying oversized organizers to cover occasional needs, reducing waste and GAS-driven impulse buys. Because the pieces are printed rather than injection molded, splitting a long rack into transportable chunks is straightforward, and broken parts can be reprinted in minutes.

The build notes included with the upload provide basic printing guidance and a reminder that fit matters – dovetail tolerances vary by printer and filament. Expect to test one module first to confirm snugness; designers commonly tweak scale or clearance to match their machine. Community members who print the rack are likely to post fit tips, remix files, and variant designs for specific bottle profiles, which will help others dial in the perfect fit.

This release highlights how small 3D projects can solve everyday bench headaches. Print one module to test fit and color-code or label as you like, then expand horizontally as your palette grows. Watch for community remixes that tune tolerances or add features such as lid holders or labeling tabs to make the rack even more workshop-ready.
