Update: I have improved and clean up the design a little so it will be better for printing.
This thing is to adapt a standart 5 mm LED to the "Edison 10 socket" (E10) mostly used in old bicycle lights. I use it to re-equip old bicycle rear lights with light bulbs to LED.
Especialy the nice old "Soubitez" from the pictures. As you can see I integrated the resistor into the light enclosure.
It is maybe not allowed to use it in bicycle lights or other vehicles
(check the law in your country) ...
you should use a external resistor and overvoltage protection to prevent the LED from
It is recomendet to use the adapter only in rear lights. And to use there bright red led's.
- You maybe have to drill out the center hole with a 1mm drillbit after printing.
Thats because of the meltet and compressed first layers.
To prevent from that you should print with 2 bis 5 layer raft.
Make sure you use low extruder temperatur, cooling and raft ...
(just as like on all small round things ;) )
