10 mm saddle clamp
Enjoy these 10 mm saddle clamps.
I used the ones I printed in nGen before getting a photo. 6 of these are holding up 18' of rope light, but one held the weight of half the strand until I added more clamps.
Don't hit these with a hammer or they'll shatter. Next time I will try nGen Flex.
Print on their side with no supports. The mounting holes match my 1" framing nails (2 mm diameter).
