I removed the clip at the end to allow for the use of a wider variety of USB powered keychain LED lights. I also added a second version that uses two keychain LED lights to in case one isn’t bright enough.
I used PETG but you can probably use PLA as long as the LED don’t get too hot and the Z axis motor doesn’t get too hot.
I used these LED’s
And these USB extension cables
