LED Disk

thingiverse

This compact LED unit has 20 LEDs housed within, accommodating required resistors (10ohm) when using a 9V battery source. The addition of hot glue effectively insulates connections, allowing it to operate smoothly. For enhanced installation or mounting options, the device features a retaining ring. This circular component enables users to mount the LED disk flush against surfaces. Two perforations are strategically placed on the reverse side for thread passage, providing versatility when securing the unit via string attachment. The diameter of the disk measures 40mm, while the retaining ring measures 48mm in circumference. A notable discrepancy is observed: the component protrudes 11mm behind the retaining ring and approximately 5mm forward. Consequently, due to their proximity to the LED unit's front edge, most colors of plastic will remain visible despite being used as a surrounding casing material.
