I love designing 3D models for my girls. Right now, they love to play with their 18" dolls (American Girl Doll and Our Generation Dolls). When looking at the price of miniature accessories for the dolls, I thought maybe I could design some myself. This is the first set I designed and they loved it. Included in this design is a small Tic Tac Toe Game Board, Snowflake and Gingerbread Man Game pieces, and a little storage drawer for the pieces.

Supplies for Resin Printing

When printing miniatures and dollhouse pieces, I absolutely love using my resin printer. The newest models of resin printers have high resolution and you can see it in the details of this print! I printed this design with an Elegoo Saturn 3 resin printer. I also highly recommend a wash and cure station if you don't already have one. I use the Elegoo Mercury wash and cure station after every print. This makes sure extra uncured resin is removed from the model and hardened. I've used both isopropyl alcohol and super strength mean green in the washing station. If you are printing designs for children, you absolutely want to make sure there is no uncured resin left on the print!

3D Printing Deals and Essentials

Where can I download the STL file?

I design and offer free STL files at Cults3D. This model is included in my free designs and you can download it here. Make sure to follow my account for updates when I post a new model!

Add Supports and Slice

If printing this model on a resin printer, you will need supports to make sure it doesn't stick to the build plate. Supports are also necessary in this print because of the model gaps for the drawer. After you download the files from Cults3d, you will need to import them into your slicer. I use the Basic Version of Chitubox. It is completely free but make sure to use the supported version of your machine. This is especially important if you are using an older 3D printer.

Add supports and a skate raft

Chitubox will add automatic supports to your models but you will want to confirm a few settings.

Light Supports

Density: 70–80%
Touchpoint Size: 0.20–0.30 mm
Upper Diameter: 0.6 mm
Lower Diameter: 0.8–1.2 mm
Connection Shape: Cone
Support Height: Auto

Suggested Raft Profile

Shape: Skate or Lava (best peel performance)
Thickness: 1.0–1.5 mm
Margin: 3–5 mm
Raft Slope: 30–45°
Raft Density: 70–90%

Slicer Settings

Slice settings are specific to your machine and the type of resin you are using. When you purchase 3D printer resin, you can look up the recommended settings for your machine and resin type. This useful resource from Elegoo has spreadsheets with this information.

Common Troubleshooting

Model Sticks to Build Plate - Did you add supports? Resin models, especially flat models, create a lot of suction with the build plate. If you have supports, try adjusting the contact shape, size, or angling your model at a 20-30 degree angle.

Model Won't Stick to Build Plate - Check your bottom exposure time and try adding time.

Model stuck to build place but not all of the model is there

- Check your exposure time and try increasing it. Exposure time is set differently for the bottom layers and the rest of the model. A longer exposure is typically given to the bottom to make sure the model sticks. If the bottom is sticking but it is failing or dropping later in the print, it might help to increase your generic exposure time.
