A holder for your folding ruler. It's pretty sturdy as it uses 4 hooks that fit snugly so it doesn't wiggle around as you pull out the ruler.
The interior dimensions are 42x18mm. I found that other similar folding ruler holders were too small for my somewhat chunky folding ruler.
I recommend printing in either PETG or PLA with 0.2mm layer height and organic supports on build plate. Without the supports, the hooks on the back won't print.
