Subwoofer Speaker Leg Replacement 4cm

Designed to fit a Jensen CS10 Powered Bookshelf Subwoofer cabinet, but easily scaled to fit other audio equipment. The original rubber leg had a steel washer to make the screw hole rigid, but I've been able to skip that piece. The screw hole should be two shells thick, which has proven durable for my purposes. 

Printing Notes:
• Any rigid plastic (such as PLA).
• No supports needed.
• Brim not needed. 
• Infill ≥ 15%.
• This sub is very light, but increase the shell thickness and infill for heavier units. 

Assembly: 
• Screw onto bottom in place of lost/broken leg.
• During use, if you hear vibration due to the leg rattling on a hard floor, add a felt sticker or glue a thin piece of rubber to the bottom of the leg. 

Today I Learned:
Popular music recorded from before the 1960s tends not to have much bass because, until then, no commercially-available subwoofers were available. Thus, studios didn't use media that could encode very low frequencies (such as reel-to-reel), which changed with the introduction of cassette tapes and 12-inch vinyl records.
