31mm festoon LED holder (Trinus rail mount!)

thingiverse

A compact 12v LED fixture (31/32mm festoon bulb) with mounting screw holes to accommodate the Kodama Trinus Z rail... The bulb can rotate downward to point at the print bed, simultaneously illuminating the extruder and highlighting the print gap for better visibility. A 6x sms SMD 3528 31mm auto Festoon Dome Light Bulb was used initially, but significantly brighter options are readily available on eBay through a search for 31mm LED festoon. The LED fixture securely attaches to the underside of the Z rail via two M1 12mm screws, identical to those utilized in the Trinus end-stop micro-switches. The print features holes that allow wire leads to pass through and make contact with the festoon bulb; a snug fit ensures electrical connection, although soldering is also an option. Its versatility extends beyond this application: the screw hole centers are 9mm apart, offering potential for various uses.
