Why I Designed This

I created this enclosure as a fun party gag for friends and family. The idea is simple:
Press one of the 10 buttons → play a random sound or music clip
From funny effects to iconic tunes like game show themes or error sounds, it’s perfect for adding humor and surprise to:

• Parties

• Game nights

• Everyday fun

The parts are assembled using M3 stainless steel countersunk screws.
