This is a simple but effective base extension for the Logitech PowerPlay 2 system, designed for users who use large mousepads and want a completely flat surface without the annoying step created by the original Logitech pad.

I made this specifically for my SteelSeries QCK Heavy Large (450 × 400 mm) mousepad.
The base is slightly smaller so you never bump into the edges while using the mouse.

Base size:
445 × 395 mm
Thickness:
2.3 mm – this matches the height of the PowerPlay system without the thin Logitech cloth pad, so your own mousepad sits perfectly flush on top.

The design is intentionally simple to keep print time low and make it easy to print, but it works exactly as intended: it supports the PowerPlay charging area and removes the height difference under large mousepads.

For best results, I recommend using glide tape or thin double-sided tape underneath to prevent any movement on the desk.

This is a practical, no-nonsense solution for anyone who wants to use Logitech PowerPlay with a large mousepad without feeling any edges or bumps.
