# 🏎️ PVC Overspray & Paint Booth Framework
|
|
|
|
### Project Overview
|
|
This repository contains the CAD files and documentation for a modular, collapsible paint booth frame. The system is designed for high-speed production on CoreXY 3D printers (specifically calibrated for the **Elegoo Centauri Carbon**) and utilizes standard PVC piping for the structural skeleton.

|
|
### 🛠 Hardware Specifications
|
|
* **Main Structure:** 1" Schedule 40 PVC ($33.4mm$ OD)
|
|
* **Stabilizer Rail:** 1/2" Schedule 40 PVC ($21.3mm$ OD)
|
|
* **Base Mounts:** 2x4 Lumber (Footers)
|
|
* **Connectors:** 3D Printed Custom Hubs (4.0mm Wall Thickness)
|
|
|
|
### 📐 Structural Components
|
|
1. **Front Hubs (x2):** 3-Way 1" sockets for the booth entrance corners.
|
|
2. **Hybrid Rear Hubs (x2):** Transitions 1" vertical/side rails to a 1/2" rear cross-brace.
|
|
3. **Floor Flanges (x4):** Heavy-duty sockets with wide-bore screw holes for 2x4 footer attachment.

### 🚀 Printing & Calibration
|
|
The integrity of this booth relies on a high-tolerance friction fit. Before printing the main hubs, you **must** perform a tolerance check.
|
|
|
|
* **Tolerance Standard:** * **1" Pipe:** $+0.15mm$ offset
|
|
* **1/2" Pipe:** $+0.20mm$ offset
|
|
* **Calibration Files:** See the [`/calibration`](./calibration/README.md) subfolder for ring-test arrays and notched identification guides.
|
|
|
|
#### Recommended Print Settings:
|
|
* **Walls:** 4 Minimum (for structural leverage)
|
|
* **Infill:** 25% Gyroid
|
|
* **Supports:** Tree Supports (Touching Buildplate)
|
|
* **Orientation:** Vertical ("Standing") to maximize socket strength.

### 📝 Assembly Instructions
|
|
1. **Foundation:** Screw the 4 Floor Flanges into your 2x4 lumber footers.
|
|
2. **Verticals:** Insert 1" PVC uprights into the flanges.
|
|
3. **Skeleton:** Connect the top 1" side rails using the Front and Rear Hubs.
|
|
4. **Stabilize:** Slide the 1/2" PVC rail into the hybrid ports on the Rear Hubs.
|
|
5. **Enclosure:** Wrap the frame in 4-mil or 6-mil plastic sheeting and secure with clips or tape.
|
|
|
|
### ⚠️ Maintenance & Safety
|
|
* **No Glue Required:** The calibrated friction fit allows for tool-less knockdown and storage.
|
|
* **Airflow:** If mounting an extraction fan, tether it directly to the 1/2" rear stabilizer rail for center-weight distribution. |
