I will design a custom 3d mold for silicone casting, resin, soap or candles
Alexandra M
About this gig
Have an idea for a soap, candle, resin or chocolate piece but no mold for it? I'll design it for you.
I create custom 3D molds from your sketch, photo or existing model. Each design is built to cast cleanly: proper draft angles so pieces release easily, even wall thickness, pour holes and air vents where they're needed.
What you get:
- Print-ready STL file (STEP on Standard and Premium)
- A preview image so you can approve the shape before you cast
- Molds sized to your measurements
- Clear notes on how to print and pour
Good for 3D-printed master molds, silicone casting, resin, wax, soap and plaster.
I don't guess. If something in your design won't release or will trap air, I'll tell you and suggest a fix before I finish.
Send me a message with your idea, the size you need and what material you plan to cast. I'll reply with a clear quote and timeline.
Note: I design the mold files. Printing, casting and shipping are not included.

I design 3D molds for makers and small businesses who need their ideas to cast, print and release cleanly. Whether it's a soap bar, a resin charm, a candle shape or a chocolate piece, I focus on the details that decide if a mold actually works: draft angles, wall thickness, pour holes and air vents. You send a sketch, a photo or a model, and I send back clear files and a preview so you know what you're getting before you cast. I reply quickly and keep every project simple and honest. Let's talk about your idea.
FAQ
Do I need to have a 3D model already?
No. A sketch, a photo with measurements or a reference image is enough. If you already have a file (STL, OBJ or STEP), send it and we can start faster.
Can the mold be 3D printed directly?
Yes, in many cases. It depends on your material and printer. Tell me what you plan to use and I'll design the mold to suit it.
Do you make the physical mold?
No. I deliver the digital design files. You can print them yourself or use a printing service, then cast with silicone, resin, wax or soap.
Which file formats do I get?
STL on every package, and STEP on Standard and Premium. If you need another format, ask before ordering.
Is the mold food-safe?
I design the shape, but food safety depends on the material you print or cast with. For chocolate or candy, use a food-grade silicone or material.
