# Plate and standoff construction

A favorite among FTC teams, plate and standoff construction uses 2D-cut flat plates spaced apart using standoffs or stacked plastic spacers. It’s intuitive, easy to service, and perfect for custom drivetrains or slide guides.

#### How It Works

* Two parallel plates form the "walls" of a structure.
* Standoffs, spacers, or bearings are used to connect and align them.
* Motors, shafts, and other hardware are mounted between the plates.

#### Pros

* **Serviceable:** Remove screws to open the assembly like a sandwich.
* **Strong and Rigid:** Parallel plates resist torsion well.
* **Easy to Design:** Plates can be laid out in 2D and stacked.

#### Cons

* **Space-Hungry:** Can get bulky in tight robots.
* **Heavy:** Metal plates and many screws/standoffs add mass.
* **Limited Adjustability:** Mounting patterns are fixed after cutting.

#### FTC Tips

* Use ⅛” aluminum or ⅛”/¼” polycarbonate plates.
* Design mounting holes on a 16mm grid to align with common FTC components.
* Add inspection holes to see bearings and shafts inside.
* Offset holes to match standoff centers—always model screw heads to check clearance.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://www.ftcwiki.org/design-style/design-methodologies/plate-and-standoff-construction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
