Step 1: What you need
1. A Cassette Tape Case (This one was problematic to find in our CD orientated world)
2. A Dremel Tool
3. Protective eye wear
Step 2: Grind away!
I used a rough grinding tool on my Dremel to slowly grind away the plastic, and then by hand remove the residue.
Step 3: Done!
You are done, just fill the hard case with your notes, you are now the proud owner of a hard case for your Hipster PDA.
A added bonus is that you have a overview page on the front of the case (if you have a see through plastic cassette case).
