Here is an offshoot of my original cassette tape case available here: http://www.thingiverse.com/thing:647517
This remix adds customizable album art templates. Believe it or not, there is a thriving tape release community among DIY and underground music labels.
This is designed to be printed without support structures with a recommended layer height of .2mm. I'm including versions with a rectangular top insert and a round top insert. Print either LogoCassette1RectangulerHole.stl or LogoCassette1RoundHole.stl, then print LogoCassette2 and LogoCassette3. Open LogoCassetteTemplate.skp in SketchUp and customize with your band's album art before printing. I recommend using one color for parts 1 and 2 and another color for the part 3 and the logos.
I am only including the pictures of the Pink Floyd Dark Side of the Moon logos as examples of what you can do. I do not own the copyright to that album art, so I can't include it here. (And please don't ask for it.)
If you customize or remix this, please list this file as the source and follow the rules of Creative Commons - Attribution - Share Alike.
Before attempting to print this, make sure your printer is well calibrated. The parts are designed to fit snugly. I recommend this calibration tool: http://www.thingiverse.com/thing:342198/#instructions
Big thanks and credit to my friend Austin Gaines for coming up with the idea.
