How to Use
Our 3D printed bath bomb moulds are easy to use and perfect for beginners or seasoned makers. Each set includes three parts: a top, a bottom, and a guide ring to help you press the perfect bath bomb every time.
Follow these simple steps:
1. Place the bottom mould on a flat surface
Sit the base piece inside the guide ring to keep it stable while filling.
2. Fill both halves with your bath bomb mix
Lightly pack your mixture into the top and bottom moulds, slightly overfilling each side. This helps form a clean seam.
3. Press the top piece into the guide
Insert the top mould (powder side down) into the guide ring and press firmly until both pieces meet. Hold for a few seconds to compress.
4. Pop it out
While holding the guide, push the top mould all the way through. This will slide both top and bottom pieces out of the ring. Gently remove each mould to reveal your perfectly shaped bath bomb.
5. Let it dry
Set your bath bomb aside to dry for 24 hours before packaging or use.

– After washing, dry thoroughly with a soft towel to avoid water spots and keep the material in top shape.

Pack, Press, Pop! Easy Steps for Perfect Bath Bombs

1. Pack the Mix
Scoop your bath bomb mixture into the top and bottom halves of the mould. Slightly overfill each side for a firm press and smooth finish.

2. Press into Guide
Place the outer guide ring around the bottom half. Insert the top half (powder side down) and press firmly until both sides meet in the centre. Hold for a few seconds to compress.

3. Pop it Out!
Push the top piece all the way through the guide to slide both halves out together. Gently lift off each mould, your perfectly shaped bath bomb should pop right out. Let it dry completely before use.
