This is a replacement for the back cover of the Wacom ExpressKey remote. I found that after nine months of daily use (including putting it in my bag) the back cover ended up chipped and loose. Since replacement covers don't seem to be available I designed my own, based on the original.

The cover fits in with a friction fit, but slight filing of the nubs or corners might be necessary to make it fit while still being snug. You may also want to add rubberized grip tape to recreate the non-stick feel of the original.

I don't know the longevity of this design yet, but so far it's extremely snug on my ExpressKey.
