(Picture is sideways, for some reason the site just does that)
A cassette tape shelf that can hold up to 5 cassettes and cassette cases. Can be fixed to wall using small nails or push pins (recommended two small nails in top, with pins in the bottom). the mounting holes are 2.5mm in diameter, with the thickness of the mounting tabs being 2.5mm. Shelves can be lined up next to each other seamlessly. The cassettes are tilted at 5 degrees to prevent them from falling out due to gravity or jolts.
This print requires no supports on most FDM printers when printed in the given orientation. The steepest overhangs are 5 degrees. PLA and ABS plastic works well, as well as any rigid plastic. Finer layer height, such as .12mm, both looks nicer and provides better structure than a courser layer height of .28mm. be wary of courser layer heights, as the cassettes may catch on layer steps due to the 5 degree angle.
