I made a dust plug for my wireless mouse to use when not charging. It has a small tab so you can actually take it out again.
This design was made for the Pwnage Ambi but can fit in most other wireless mice as the hole is more or less similar. STEP and f3d files are included in case you want to modify the design, or an STL if you just want to print it.
The author marked this model as their own original creation.
