## Introduction
|
||||
|
||||
Making custom trapdoors is an often difficult task to do, but after reading this tutorial you'll understand how they work in case you find any drawbacks during recreating them, and you'll be provided with a template for you to use.
|
||||
|
||||
## Custom Trapdoor
|
||||
|
||||
This will create a vanilla-like custom trapdoor.

:::tip
|
||||
Vanilla trapdoors have a few issues in the direction of the texture in certain faces and having a height of 2.95 when it should be 3. This block template and geometry fixes both of those issues.
