DruckWerk

A professional 3D printer enclosure documentation site built with SvelteKit.

About

DruckWerk documents the construction of a professional 3D printer enclosure built from an IKEA table. The enclosure features:

• Fixed 230V power input via IEC C14
• Internal AC distribution via WAGO terminals
• Dual-output PSU (12V + 5V)
• ESP32 control with PWM for LEDs and fans
• Home Assistant integration
• Cleanly separated AC and DC zones
• BME280 temperature and humidity sensor
• 4x 120mm PWM fans (1 intake, 2 exhaust, 1 carbon filter)
• Detachable top plate with vibration-isolating leg shoes
• Base plate system for stability

Mechanical Design

Leg Shoe System

• Upper shoes: Mount to removable top plate, 100mm sleeve with foam rubber lining for vibration isolation
• Lower shoes: Cup design for base plate, centers and stabilizes table legs
• Base plate: 550x550mm multiplex/plywood (12mm)

3D Printed Parts

All printed parts designed for PETG/ASA:

• Corner brackets (12x)
• Door hinges, handle, stops
• WAGO holders (221-413 for AC, 221-415 for DC)
• AC zone cover plate
• Leg shoes (upper & lower, 4x each)
• Cable strain relief

Smart Home Integration

ESPHome Configuration

Complete ESPHome config included with:

• PWM control for LEDs (3 kHz) and 4 fans (25 kHz)
• BME280 I2C sensor (temp, humidity, pressure)
• Physical buttons for light toggle and fan boost
• Overtemperature protection (>45°C triggers max cooling)
• Boost mode script (10 min high-speed ventilation)

Home Assistant Automations

Ready-to-use automations for:

• Material-based fan profiles (PLA, PETG, ABS)
• Overtemperature failsafe with notifications
• Post-print carbon filter run (15 min for ABS)
• Default enclosure state management
