LED Double Strip Holder

I was looking for a simple LED support but allowing to put two strips next to each other. The design is based on https://www.thingiverse.com/thing:2387112 but as I did have tight margins I put the screw holes (two sets in fact) below the strip. The screw holes are suitable for 3.5 mm wood screws.

Two files are attached, one for a short version (~14 cm) and a longer one (~21 cm) that you might have to print diagonally, depending on your printer. Note that the 14cm version perfectly aligns with two sets of cut marks on the LED strips while the 21 cm version has no such alignment.
