Learn how to make a custom dildo with a Clone A Willy kit. Step-by-step instructions for the Jet Black and Glow In The Dark kits, plus tips for success.
Quick answer
Making a DIY dildo with a Clone A Willy kit is straightforward: mix the alginate powder with water, create a mold of your anatomy, let it set, then pour the silicone and insert the included mini vibrator. The key is following the timing and temperature exactly.
Which kit should you choose?
The Clone A Willy Jet Black Kit Black creates a classic, discreet black vibrator, while the Glow In The Dark Kit Green adds a playful, luminous effect. Both include the same molding powder, thermometer, and mini vibrator. The main difference is the final color and novelty factor.
If you're a larger size, consider buying an extra bag of Clone A Willy Moulding Powder 85g to ensure you have enough alginate to fully submerge the area. The standard kit works for average dimensions, but bigger builds may need more material.
Step-by-step instructions
- Prepare your materials and space: Gather your Clone A Willy kit, a mixing bowl, warm water (around 95°F / 35°C as measured by the included thermometer), and a container tall enough to submerge the area. Work in a comfortable, warm room to avoid the mold setting too quickly. Check the water temperature carefully—too hot or cold ruins the mold.
- Mix the alginate molding powder: Pour the entire bag of alginate powder into the mixing bowl. Add the measured warm water and stir vigorously for about 60 seconds until the mixture is smooth and free of lumps. Work quickly because alginate begins to set in 2-3 minutes. Don't over-mix; lumps can create air pockets in the mold.
- Create the mold: Immediately after mixing, submerge the erect area into the alginate mixture. Hold still for 3-4 minutes while the mold sets. Keep your body relaxed and avoid any movement that could distort the shape. Any movement during setting will ruin the mold—stay perfectly still.
- Remove and prepare the mold cavity: Once the alginate is firm (like a stiff jelly), carefully wiggle free. You'll have a negative impression. Rinse the cavity with water to remove any residue, then dry it gently with a clean cloth. Be gentle—alginate is fragile and can tear if handled roughly.
- Mix and pour the silicone: Open the silicone bottle and pour it slowly into the mold cavity. Tap the sides of the mold to release air bubbles. Insert the mini vibrator into the silicone at the base, ensuring the battery compartment stays accessible. Pour slowly to minimize bubbles; trapped air creates weak spots.
- Let the silicone cure: Allow the silicone to cure undisturbed for at least 8-12 hours (or overnight). The exact time depends on room temperature—warmer rooms cure faster. Do not rush this step. Curing too quickly or too slowly can make the toy sticky or weak.
- Demold and enjoy: Once fully cured, carefully peel away the alginate mold. Rinse the finished vibrator with warm water and mild soap. Insert batteries into the mini vibrator and test the functions. If the mold sticks, soak in warm water for a few minutes to soften the alginate.
