Logitech K400r Mounted Mouse Pad

This remixes the swivel sim rig keyboard mount found on Thingiverse by basically reversing it so instead of the bracket mounting on the under side, it mounts over the entire top side. It covers the track pad and gives you a small mouse pad extension you can use a mouse on.

Includes access to the power switch and slides on and off without being too tight or too loose.

Comes in two parts, the bracket and the mouse pad. Both are printed at 0.3mm layer height. Print the bracket sideways, then print the mouse pad, flip it bed side up so the smooth side is facing upwards, and then weld the two pieces together either by friction welding with a Dremel or with a 3d printer pen.

If you prefer, you can cut and glue a mouse pad to the plastic part. My mouse worked fine without it.
