I don’t have my finger on the source, but I found this clip for mounting LEDs on the 2020 slot. I redrew it, because my leds are a little bigger.
But the neat thing is, it is printed in vase mode (with zero bottom layers) and it ends up being perfectly flexible and very quick to print. Plus, it doesn’t use much plastic.
Maybe it will inspire some of you to do something similar to solve a problem.
