Small single-piece 3D-printed bath bomb mold now available

Designer mold2molds published a ready-to-print STL titled "I'm Lovin' You Smile," a compact single-piece bath-bomb mold that makers can 3D-print and use straight away. The file lists precise model dimensions of X 69.7 × Y 80 × Z 31.8 mm and lays out a simple intended workflow: 3D-print the mold, pack bath-bomb mixture into the cavity, let set, and unmold. The listing includes printing notes that the model is a one-piece print and typically requires no supports, plus the designer’s usage and licence terms. The page also shows views and downloads and includes the publication timestamp of January 8, 2026, 07:06 UTC.

This matters because small-format, single-piece molds remove several barriers for makers who prefer printing their own tooling rather than ordering silicone. A one-piece STL like this is useful for single-shot gift production, small-batch runs, seasonal testers, or rapid prototyping of new shapes without the time and cost of silicone tooling. For crafters who want to drop a ready-made decorative impression into the tub, a print-and-pack workflow speeds things up and keeps overhead low.

Practical details are front-and-center in the listing. The exact dimensions let you confirm finished bath-bomb size before printing; at roughly 70 by 80 millimeters and 31.8 millimeters deep, this is squarely in the small bath-bomb category. The one-piece, no-support print callout simplifies setup for common FDM printers and reduces post-processing. The designer’s licence terms are included with the file, so verify allowed uses before selling items made with the mold.

For community makers who want to adopt the mold quickly, start with a test print at the listed scale to confirm fit and extraction. Follow the designer’s print notes and your usual printer calibration routine. Verify the licence terms if you plan to produce items for sale or wider distribution. Because the mold is compact and printed as a single part, consider running multiple prints in parallel if you want modest batch output without making silicone duplicates.

The takeaway? This STL is a low-friction option for makers who want quick-turn decorative molds without ordering custom silicone tooling. Our two cents? Print a single test unit first, double-check the licence, and use the mold for sample runs or gift batches before committing to larger production.
