Wrist Rest Mouse Pad

Here's a 3D model to print your own custom hard mousepad. It has a curved wrist rest, originally designed around a Corsair mouse, but it should work well for most other mice too. This makes it much more ergonomic to use a mouse as you never have to hold up your wrist. After printing, you'll need to sand the top smooth for the best mouse glide and add your own non-slip material to the bottom so it doesn't slide around your desk.

Design Features:

• Integrated Hard Surface: The print itself forms the mousing surface 
• Curved Surface: Features a gentle curve for comfort/ergonomics.
• Customizable Base: Requires adding a non-slip base material.

Printing Tips & Recommendations:

• Filament: Standard filaments like PLA, PETG, or ABS work. PETG or ABS might offer better long-term wear resistance.
• Layer Height: Use a standard layer height (e.g., 0.2mm). For the final top layers, consider a smaller height (e.g., 0.1mm - 0.12mm) or your slicer's "ironing" feature to get a smoother starting point before sanding.
• Infill: 15-25% should be fine for rigidity. Use more if you want it heavier.
• Perimeters/Walls: 3-4 perimeters are recommended for durability.
• Bed Adhesion: Very important for large flat prints!
  • Clean your print bed well.
  • Consider glue stick, hairspray, or other adhesion aids.
  • An enclosure helps prevent warping, especially for ABS/ASA.
• Orientation: Print flat on the bed, top side up.

Build Instructions & Post-Processing:

You need to finish the print for it to work well:

Top Surface Smoothing:

• Layer lines on the raw print might mess with mouse tracking. Sanding is the best fix.
• How to Sand: Start with medium sandpaper (150-220 grit) on a block to flatten the surface. Then use finer grits (400, 600, 800+) until it's very smooth. Wet sanding can help get an even smoother finish.
• Other Ideas: Ironing might help a little but often isn't perfect. Sticking on a separate surface material works but can be tricky to apply perfectly flat. Sanding gives a solid, integrated feel and will last longer.

Adding Bottom Grip (Essential):

• The plastic bottom will slide everywhere. It needs grip.
• Best Method: Cut up an old cloth mousepad and glue it to the bottom (contact cement or E6000 works well). Make sure it covers most of the base.
• Other Ideas: Glue on thin cork sheet, thin rubber sheet, or stick on rubber feet/strips.

Final Result:

After printing, sanding the top smooth, and adding grip to the bottom, you'll have a custom hard mousepad ready for smooth tracking!
