A remix of my LED strip holder for 2020 extrusion. I redesigned the model to make the dimensions whole numbers and not 16 decimal places long (it's not important, but I did spend an hour remodeling it from the ground up!)
It mounts with countersunk M4 screws and T-nuts in 2020 extrusion. This should also work with 3030 extrusion.
Recommend printing with three perimeters
(3) M4 T-nuts
(3) M4 x 10mm flat head screws
