Notes:

My wife loved her old magnetic torch with an incandescent bulb and there were others laying around. So rather than send them to land fill, I printed this housing in which you insert a LED with the + positive leg usually on the inside and the -negative leg on the outer side. Then if your terminals are the right way for the power to flow bend the legs just a little to fix them in place and contact where the old bulb would have to receive power and your old torch shall have new ligh....I mean life.
In the images, note you can see the red torch has 2 LEDs one violet and one white to demo it working and you can get your torch in any colour you like (Floyd-ish I know). With this one running on D cells, anyone care to tell me how long it will last?
The print is orientated correctly to print well like it is (mushroom like) I recommend printing with a 10mm brim for stability and a bit of adhesion. I used ABS for this run with abs juice for adhesion on a heated bed.
