How to build 3D models in Minecraft – convert STL or OBJ into a Litematica schematic

Updated: October 24, 2026

A statue, a spaceship or a character from a film – almost any 3D model can be rebuilt in Minecraft. The trick: the model is converted into a Litematica file. In the game, Litematica then shows you a see-through preview of where every block goes.

1. Find a suitable model

Models made for 3D printing work best – they are closed, without holes in the surface. You can find many free models on Printables, Thingiverse and MakerWorld, for example. Download the file as STL or OBJ and respect the license: many models may only be used privately.

If a model does have holes, the converter fills the gaps where it can and lets you know.

2. Convert it into a .litematic

1. Open the STL → Litematic converter and upload your model.
2. Choose the size: you set the longest side in blocks; the other sides follow. About 64 blocks is a good start for statues. Twice the size needs about eight times as many blocks.
3. Choose the block: the whole model is built from one block, for example stone, quartz or concrete in one colour.
4. Turn on hollow if you build in survival. Only the outer layer remains – that often saves three quarters of the blocks.
5. Click “Convert”. The 3D preview shows the block model, and below it you see the blocks you need in stacks and shulker boxes.

3. Load it in Litematica

1. Copy the downloaded file into the .minecraft/schematics folder.
2. In the game, press M to open the Litematica menu and choose “Load Schematics”.
3. Select your file and click “Load Schematic”. The model appears as a see-through preview at your position.
4. In “Schematic Placements” you can adjust the exact position and rotation.

4. Build it in survival or creative

• Material list: Litematica shows a “Material List” with all the blocks you still need.
• Layer by layer: with the “Render Layers” settings you show only one level at a time, so you do not lose track on big models.
• Easy Place: in “Easy Place” mode, a click places exactly the block the preview shows at that spot.
• Creative mode: here Litematica can paste the model straight into the world with the “Paste Schematic in World” tool mode.

Tips

• Round shapes look smooth from about 48 blocks in size; smaller models look more “pixelated”.
• Thin parts such as swords or antennas become at least one block thick.
