3D template that simplifies mold making.

Create professional-grade silicone molds, save time and money, and start casting concrete decor with ease.

Let's face it, finding a mold is the most stressful part of making concrete decor pieces!

When I first started making concrete decor pieces, I had no idea how important molds were in the creating process. I still remember the frustration of searching for the perfect mold. And every time I found one, it was either too expensive, poorly made, or didn’t match my vision.

Then one day I woke up and said, What if I made my own molds?

That same day, I sketched my design on paper, turned it into a 3D model, and then 3D-printed the model. With just one 3D-printed model, I created 35 perfect silicone molds for only $67 and saved nearly $250 in the process. 

Today, I want to share that 3D model with you and make it just as easy for you.

Why I’m sharing this model with you

When I started my concrete journey, I didn’t have access to a resource like this. Every step felt like a challenge.

But after creating countless molds, I realized that I could simplify this mold making process for others. So my goal is to simply help you skip this trial and error phase and go straight to creating molds in just a few simple steps.

Imagine you could…

  • Create professional-grade molds
  • Save money and time by making your molds at a fraction of the cost.
  • Make quality molds without needing 3D modeling skills.

I get it! I’ve imagined that too.

What is this solution?

The solution is a 3D-printable bubble coaster master model (template) designed to simplify mold-making for concrete decor. It’s a ready-to-print STL file and the design comes with a built-in mold box, allowing you to create professional-grade silicone molds easily. This is the exact master model I used to make all my molds for my coasters. 

Why this model is the perfect solution to your problems?

I remember the frustration of trying to create my first mold. After countless attempts, I finally turned to 3D printing my master model. That decision completely transformed the trajectory of my production.

Perfect beginner project

This bubble coaster model is the perfect way to kick off your concrete decor journey. It simplifies creating your first mold and helps you start building your product line.

Has a built-in mold box

The 3D model comes with a built-in mold box which makes pouring silicone rubber more quick and easy, and also provides a consistent shape for every mold you create.

No design skills required

Skip the frustration of learning 3D modeling. The design work is done for you. This file is ready for download.

You’ll save money

Make multiple molds with just one 3D- print and without breaking the bank. Print once, use multiple times.

Just download and print

The model is ready for download and print. And the file is compatible with standard 3D printers

Here’s how it works

Make a purchase. Once the purchase is complete, you’ll get immediate access to the digital file via email, ready for download.
Step 1 Download the STL file
Print the 3D model. Just send the file to your local 3D printing service, and they’ll print it for you. The STL file is compatible with standard 3D printers.
Step 2 Print the 3D model
Use the 3D-printed model to make a silicone mold. Pour silicone rubber inside the model box until it’s full. Let it cure, then remove the mold from the model.
Step 3 Pour silicone rubber
Once the silicone mold is ready, use it to make your concrete coasters. Pour your concrete mix inside the mold, let it cure, then demold your finished concrete piece.
Step 4 Making concrete pieces

Frequently Asked Questions

Absolutely. This STL file is designed for anyone to use, even if you’ve never made a mold before.

Not necessarily. You can use a local 3D printing service to print your model. Just email them the STL file and have them print it for you.

Yes, the STL file is a universal format compatible with most 3D printers.

Depending on your printer and the model size, 3D printing can take a few hours, but many 3D printing services offer quick turnarounds.

You’ll need silicone rubber (available online or at craft stores) and the 3D-printed model.
