This is a remix for a 10mm wide led strip. The speciality of it is it can hold 2 led strip next to each other for bigger light. The other is it hold these strips in 22.5 degree angle. It's really decorative, looks natural angle. But for example in my case I used it to hold my strip horizontally in a non-horizontal roof.
(I designed a single version too, but that not printed / tested)
Can print in better resolution, but I'm thinking for this usually don't need it, print time is more important.
