The Apple Interface Cyberdock is a lapdock/ docking station/ human interface device intended to get all the tools you need into a small form factor.

By wiring the Apple Keyboard and Trackpad into a USB-C hub, you can connect your human interface devices to any host that supports USB-C input (Laptop / Desktop / tablets / Steam Deck, etc.) The Cyberdock features 3 display out connectors, ethernet, SD card readers, analog audio, and additional USB ports. 

Chassis prints in a single piece, and no supports necessary for any parts. This design uses off-the shelf components, so no electronics skills necessary.

The staggered keyboard/trackpad design puts gesture-based controls (scrolling, zoom, desktop swapping) within easy reach of the left hand, making it convenient to use with a traditional mouse.

The chassis features regularly positioned mounting holes, making it compatible with additional accessories.

Supported Technology:

• Apple ‘wedge’ style Magic Keyboard, A1644
• Apple ‘wedge’ style Magic Trackpad, A1535
• PENGLIN USB 3.1 Type C Panel Mount Coupler, D-Type Module USB C Pass Through Connector, Female to Female Bulkhead Extension Adapter
• USB C Right Angle Adapter, 90 Degree Type C Male to Female Adapter Extender Support 40Gbps Data

Additional Resources: 

• x19 m3 4mm heat-set inserts
• x2 m3 8mm screws (for holding devices snug, more needed if you want to attach stuff)
• x8 10mm adhesive rubber feet

I've spent hundreds of hours, and hundreds of dollars in filament to develop and test this.
